In chickens, the allele for a pea comb (A) is dominant to the allele for a single comb (a). A mother with the genotype Aa and a
zloy xaker [14]

Answer:

The percent chance that the offspring will have a single comb is 25 %

Explanation:

Given,

The allele for single comb represented as "a" is recessive to the allele for pea comb represented as "A"

Genotype of male - Aa

Genotype of female - Aa

Gamete of Male - A, a

Gamete of female - A, a

Cross between Aa and Aa will produce

AA, Aa, Aa, aa

Thus, out of four offspring only one has "aa" genotype and hence this individual will express the recessive trait i,e  aa

The percent chance that the offspring will have a single comb is

\frac{1}{4} * 100\\

25 %

SDS (sodium dodecyl sulfate) PAGE ( Polyacrylamide gel electrophoresis) is the technique of the separation of the molecules on the basis of their molecular weight.

The beta-mercaptoethanol reduces and break the disulfide bonds present in the protein. When the protein X with the beta-mercaptoethanol is allowed to run on the gel, only one band will visible all the subunits have equal weight and will present at the same location on the gel.

Thus, the answer is one.
