A flowering plant species' seeds can either be colorless (white) or green, with the feature being governed by two independently assorting loci. At one site, the dominant G allele causes green color.
When a green-seeded plant crosses with a heterozygous plant, does the yellow seed color become dominant over the green seed color?Half of the offspring from a heterozygous yellow-seeded and green-seeded plant hybrid will be yellow and half will be green.
Is the gene for yellow seeds more prevalent in pea plants than the allele for green seeds?The seed color of pea plants is a classic illustration of total dominance. This indicates that the phenotype can arise from the dominant allele with only one copy present. A recessive allele requires two copies to exist. In terms of seed color, the green allele (Y) is recessive while the yellow allele (Y) is dominant.

In order of fastest to slowest, the chemical buffer system, respiratory system, and renal system.
When little amounts of an acid or a base are introduced, a chemical buffer system prevents the pH of the solution from changing. Weak acids and their salts or weak bases and their salts make up this substance, which aids in preserving a steady pH level in the body. In order to provide the body with oxygen and expel carbon dioxide, a network of organs and tissues is called the respiratory system. The diaphragm, bronchi, lungs, larynx, nose, mouth, and throat are all included in it.

The characteristics of allergic purpura are fever and itching, easily palpated lesions. The correct option is Option A.
Henoch-Schoenlein purpura (also known as IgA vasculitis) is a common disorder that causes the small blood vessels under the skin, joints, intestines and kidneys to become inflamed and tend to bleed. Purpura lesions are generally itchy and fever can also occur due to these lesions. They are raised and are usually easily felt. Bleeding from the lesions themselves and generalized bleeding are uncommon. The lesions due to purpura tend to be found on the proximal extremities, especially on the legs and buttocks. The identifying feature of this form of vasculitis is the appearance of purplish rash, typically found on the lower legs and buttocks. It can also lead to abdominal pain and aching joints.

On a chromosome, a section of DNA sequence coding for information for a feature of an organism, such as flower color, is a gene, and different versions of this sequence, which impact a feature are called alleles.
A DNA sequence is a precise arrangement of the (deoxyribonucleotides) building blocks of DNA, which contain four distinct nucleotides: adenine (A), guanine (G), cytosine (C), and thymine (T). The sequence of nucleotides in a DNA sequence encodes genetic information that cells employ to generate certain proteins and execute various activities. The letters A, G, C, and T, which represent the nucleotides in the sequence, are commonly used to symbolise the DNA sequence. The genetic information stored in the DNA sequence is determined by the exact arrangement of these letters.
A gene is a piece of DNA that codes for a certain attribute or feature of an organism, such as flower colour. Alleles are different forms of the same gene that might result in phenotypic differences. In the instance of flower colour, for example, various alleles might result in different colours such as red, blue, or white.

In guinea pigs, rough coat (R) is dominant over smooth coat (r). A rough-coated guinea pig is bred to a smooth coated one, yielding seven rough and six smooth progeny on the F1 generation.a) What are the genotypes of the parents and the offspring?b) If one of the rough-coated F1 animals is mated back to its rough-coated parent, what progeny would you expect?
a)We can use Punnett squares to determine the genotypes of the parents and offspring: Let's represent rough coat (R) as dominant and smooth coat (r) as recessive.
The rough-coated parent must be RR, as it is homozygous dominant. The smooth-coated parent must be rr, as it is homozygous recessive.
Rough-coated parent (RR) x smooth-coated parent (rr):
R R
r |Rr Rr
r |Rr Rr
All of the F1 progeny are heterozygous for rough coat (Rr).
b) If one of the rough-coated F1 animals is mated back to its rough-coated parent (RR), the Punnett square would be:
Rough-coated F1 (Rr) x rough-coated parent (RR):
R R
R |RR RR
r |Rr Rr
We expect to see a 1:1 ratio of rough-coated (RR and Rr) and smooth-coated (rr) offspring in this cross. Therefore, we would expect half of the offspring to have rough coats (Rr) and half to have smooth coats (rr).
