Chromosome number can evolve by smaller-scale changes than duplication of entire chromosome sets. For example, domestic horses have 64 chromosomes per diploid set while Przewalski's horse, an Asian subspecies, has Przewalski's horse is thought to have evolved from an ancestor with chromosomes. The question is: Where did its extra chromosome pair originate?

Answers

Answer 1

The extra chromosome pair in Przewalski's horse (Equus przewalskii) likely originated from a chromosomal fusion event. Chromosomal fusion occurs when two separate chromosomes, each with their own centromere, become fused together to form a single chromosome with a single centromere.

In the case of Przewalski's horse, it is thought that the ancestor had a diploid chromosome number similar to that of domestic horses (64 chromosomes). However, at some point in the evolutionary history of Przewalski's horse, a fusion event occurred, leading to the formation of one large chromosome by the fusion of two smaller chromosomes.

The specific details of which chromosomes fused in Przewalski's horse are still being studied and researched. However, chromosomal fusions are known to occur through various mechanisms, such as Robertsonian translocations or non-homologous end joining (NHEJ) repair processes.

The fusion event resulted in a reduction in the total chromosome number, with Przewalski's horse having one less pair of chromosomes compared to domestic horses. This illustrates that changes in chromosome number can occur through smaller-scale events, such as chromosomal fusions, rather than duplication or loss of entire chromosome sets.

What is the best evidence to
prove that Irene was heterozygous for hemophilia?
Elizabeth IS not a carrier for the trait.
Tatiana carried the recessive allele.
Her brother has
hemophilia and her sister is a carrier.
Two of her sons have hemophilia and one does not.

Answers

The best evidence would be two of her sons having hemophilia while one does not.

Hemophilia

Hemophilia is a sex-linked recessive disorder. This means that females can be homzygous normal, heterozygous, or affected by the disorder while males can either be normal or affected.

Why? This is because males have only one X chromosome (XY) while females have 2 X chromosomes (XX).

Also, the X chromosomes in males are always from their mothers while their Y chromosomes come from the father.

So, if the two X chromosomes of Irene are normal for hemophilia, none of her sons should be affected. If the two X chromosomes are affected, all her sons will have the disorders.

When one X chromosome is affected and the other is normal, it means that some of her sons will inherit the affected chromosome and have the disorder while some will inherit the normal chromosome and will be free from hemophilia.

#SPJ1

The strongest evidence that Irene is heterozygous for the condition is the fact that two of her boys have hemophilia and one does not. Because hemophilia is an X-linked recessive disorder, the X chromosome plays a role in its genesis. Males only have one X and one Y chromosome, whereas females have two X chromosomes.

If Irene were homozygous for the normal allele (non-carrier), none of her boys would receive an incorrect X chromosome, preventing them from developing hemophilia. If Irene were homozygous for the hemophilia allele (affected), all of her sons would be affected by the disease since they would inherit her X chromosome.

However, Irene may be a carrier of the hemophilia allele given that two of her sons have the condition while one does not. As a transporter, she has one typical X chromosome and one X chromosome conveying the hemophilia allele. She can pass either the typical or the hemophilia allele to her posterity, bringing about a blend of impacted and unaffected kids.

The residual air is the amount of air remaining in the lungs after a forced expiration. The volume of air exchanged during normal breathing is called the tidal volume. After a normal inspiration, the amount of air that can then be inspired forcefully is called the inspiratory reserve volume. The total lung capacity minus the residual volume equals the vital capacity. The vital capacity minus the expiratory reserve volume equals the inspiratory capacity. The effects of obstructive disorders, such as asthma or emphysema, may be determined by measuring rapid exhalation with a spirometer.

The lungs are the main organs of the respiratory system. These lungs are also the site of exchange of gases. The air is inspired through the nostrils and this air then reaches the lungs, where the oxygen from air is trapped in the alveoli. This oxygen then diffuses into the bloodstream through capillaries, which is then sent to the heart. From the heart this oxygenated blood travels to different parts of the body.

Which statement BEST describes how greenhouse gasses act as natural insulators in the Earth's system?

Answers

Hi there, your answer is below.

The gases absorb and emit a part of the heat reflected by the Earth's surface.

Solar radiation will pass through the atmosphere first in the greenhouse effect. Some of them will get through and touch the surface of the planet. Long-wave thermal radiation, which is what the greenhouse gases will absorb, will be produced when some of the energy that strikes the Earth's surface is transformed. They are returned to the Earth via greenhouse gases.

What are greenhouse gases, and why do they affect our environment?

The surface of the Earth would be much colder and have a "snowball Earth" if it weren't for the impact of greenhouse gases, primarily water vapor, carbon dioxide, and methane.

Because the greenhouse gases are generally transparent to the sun's incoming radiation, which is mostly in the visible light region of the spectrum, the greenhouse effect is able to take place. In contrast, the majority of the radiation that the Earth emits is in the infrared region of the spectrum, which is absorbed by greenhouse gases. Some of the radiation from these gases is redirected to the earth when it is later released. This traps it, warming the planet's surface in the process. The average temperature of the Earth would be -14 degrees Celsius without greenhouse gases.

Greenhouse gases have acted to even out temperature changes over Earth's history. Huge woods have thrived when the Earth experienced warmer times, as the Carboniferous epoch. These have taken in carbon dioxide from the air, storing the resultant carbon in the form of coal deposits underground. After a certain amount of carbon has been stored, the atmospheric concentration of carbon dioxide falls to very low levels, and the warming effect is eliminated. The trees perish as the globe cools.  Currently, plants are no longer removing carbon dioxide from the atmosphere, while volcanoes are still adding carbon dioxide to the atmosphere. The increase in carbon dioxide causes a rise in global warming. We are now recuperating from the last glacier, which ended roughly 10,000 years ago, during a mild time. In the past 120,000 years, the previous warm era peaked.

The ability of carbon dioxide to boost plant development is another crucial effect. Without the impact of the increased carbon dioxide concentration on crops, it is improbable that the Earth could support the 7 billion people that inhabit it now.

The amount of carbon stored in the atmosphere is rather tiny. There are currently 800 billion tons of carbon in it. But only approximately a quarter of this, or 210 billion tons, of the carbon gets recycled each year by plants and the seas. Consequently, the two-year half life of carbon in the atmosphere is rather short. Because there is such a tiny atmospheric carbon storage, people have a significant impact. Burning fossil fuels only adds roughly 9 billion tons annually. But throughout my lifetime, the concentration has increased by 30%, from around 300 parts per million in 1947 to 410 parts per million now, as a result of this modest increment each year. As a result, there has been a little but considerable increase in surface temperature as well as rising sea levels due to ice cap melting. Although the increase in sea levels over the past 70 years has only been around 9 inches, it is rising, and because so many people live near the coasts, we are susceptible.

Because the atmospheric carbon storage is so limited, it is possible to lower atmospheric carbon and prevent flooding in our coastal communities, for example by fertilizing the seas to improve their capacity to absorb carbon dioxide.

Eddie

Answers

Therefore, when the alleles of a particular gene are passed on to their descendants via gametes, a haploid sperm fertilizes a haploid egg producing a diploid zygote.

The process in which haploid gametes fuse to form diploid offspring:

A diploid cell produces haploid cells during meiosis, and two haploid cells (gametes) combine during fertilization to create a diploid zygote.

Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes, which results in the production of gametes, such as sperm or egg cells. Meiosis comprises two rounds of division, producing four cells with only one copy of each chromosome as a final product (haploid). Additionally, each chromosome undergoes genetic material cross-pollination between the paternal and maternal copies before division, resulting in novel combinations of the genetic code on each chromosome.  The haploid cells created by meiosis between a man and a female will later unite during fertilization to create a cell with two copies of each chromosome once more, the zygote.
