Answer: yes atom is the smallest level of organization

Explanation:

The Hardy-Weinberg equation, which assumes that the population is in genetic equilibrium, may be used to determine the predicted allele frequencies in a population.

Since only those who have two copies of the dominant allele may display the dominant phenotype, the frequency of the homozygous dominant genotype (p-2) is equal to the frequency of the dominant phenotype, which is 0.64.

In order to find p, we may utilize the equation as follows:

[tex]p^2 = 0.64[/tex]

[tex]p = \sqrt{0.64} = 0.8[/tex]

As a result, it is projected that the dominant allele (p) has a frequency of 0.8, whereas the recessive allele (q) has a frequency of:

q = 1 - p = 1 - 0.8 = 0.2

Therefore, p=0.8 and q=0.2 are the expected allele frequencies under this group.

Explanation:

An rise in contractility typically results in an increase in stroke volume and, as a result, preload. As according Starling's law of a heart, a rise in preload causes an increase in the force of contraction.

The intensity of myocyte contract, also known as inotropy, is referred to as contractility. The volume of the heart's stroke grows even as force of contraction rises because the heart can circulate more blood out of it.

A- The parental genotype is VvPrBm/vprbm. The double crossover genotypes are Vvprbm/vprBm and vprBm/Vvprbm.

B. There are 40 recombinant offspring out of a total of 784 offspring. This gives a recombination frequency of 40/784 = 0.051, or 5.1%.

the recombination frequency between v and pr is 2/784 = 0.003, while the recombination frequency between pr and bm is 3/784 = 0.004. Since the recombination frequency between v and pr is lower, we can conclude that v is located closer to pr than to bm. Therefore, the gene order is v-pr-bm.

C. the recombination frequency between pr and bm is 0.004. Therefore, the genetic map distance between v and pr is 0.003 map

The total genetic map distance between v and bm is the sum of the distances between v and pr and between pr and bm, which is 0.003 + 0.004 = 0.007 map units.

The genetic map of the three loci is as follows:

Answer:

A. a way to test for chromosomal mutations

Explanation:

You're welcome.

We define karyotype as the set of chromosomes contained in the cells of an organism.

Morphologically, these chromosomes are identified, differentiated and classified according to the size and location of the centromere (region of the chromosome intermediate to the symmetrical or asymmetrical, short or long arms).

Classification of chromosomes:

Metacentric → Centromere positioned at the center of the chromosome; Submetacentric → Centromere displaced to one end of the chromosome; Acrocentric → Chromosome bearing a terminal sphere (satellite), located at the end of the short arm; Telocentric → Chromosome formed by only one arm, with strictly terminal centromere.

In order to determine and visualize the karyotype, making it possible to quantify the typical number of chromosomes of a species, it is necessary to interrupt the cell division process at the time of metaphase, the phase in which the chromosomes reach the maximum condensation.

In the human species, the karyotype of a diploid cell, for example, consists of 46 chromosomes, the last sex-defining pair (XX or XY – allosomal pair), differing the male and female gender (man and woman) and the other 22 pairs (autosomal - AA) responsible for decoding the other characteristics.

Thus, we have for a normal karyotype of the human species, the following possible representations:

Male karyotype → 22AA + XY or 46,XY

A woman's karyotype → 22AA + XX or 46,XX

Since the m/v (mass/volume) ratio of solution B is higher than that of solution A, therefore the semi-permeable membrane will cause the decrease in volume of solution A due to osmosis.

Osmosis is the process of movement of solvent particles from the region of their higher concentration to the region of lower concentration through a semi-permeable membrane. It can be conversely said that the movement of solvent occurs from low solute region to high solute region.

A semi-permeable membrane is a thin membrane which allows the transfer of only solvent and very small sized molecules through it. Large sized solute particles cannot pass through it.

The founder effect, in which a small group of people departs from their native population and finds a brand-new, isolated community, is one factor contributing to genetic drift.

The founder effect, in terms of genetics, is the reduction in genomic variability that occurs when a small population splits off from a larger one. In terms of genotypes and physical characteristics, which may be very different from the original bigger population, the resulting new subpopulation will eventually resemble the original small, isolated group. The fact that some subgroups of the population are more likely to have certain genetic illnesses may also be explained by the founder effect.

Climate is the general weather patterns of a region studied for many years. The climate, on the other hand, affects the ecosystem of regions influencing the kind of plants and animals that it inhabits.

This is because it is natural for life to become adapted to specific climatic regions due to natural selection and evolution creating different species across different regions.
