you make a punnett square for a cross and find the results shown below.\nyour prediction is that of the offspring would have the dominant phenotype, and of the offspring would have the recessive phenotype.

you make a punnett square for a cross and find the results shown below.\nyour prediction is that of the offspring would have the dominant phenotype, and of the offspring would have the recessive phenotype.

Answer

Explanation:

Step1: Count total genotypes

There are 4 genotypes in the Punnett - square.

Step2: Count dominant genotypes

The genotypes with the dominant phenotype are homozygous dominant (XX) and heterozygous (Xx and xX). There are 3 such genotypes.

Step3: Calculate proportion of dominant phenotype

The proportion of offspring with the dominant phenotype is $\frac{3}{4}=75%$.

Step4: Count recessive genotypes

The genotype with the recessive phenotype is homozygous recessive (xx), which is 1 genotype.

Step5: Calculate proportion of recessive phenotype

The proportion of offspring with the recessive phenotype is $\frac{1}{4}=25%$.

Answer:

75%; 25%
