Question

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

Explanation:

Step1: Identify genotypes for dominant phenotype

In the Punnett - square, the genotypes that show the dominant phenotype are homozygous dominant and heterozygous. There are 3 such genotypes out of 4 total genotypes in the Punnett - square.

Step2: Identify genotypes for recessive phenotype

The genotype that shows the recessive phenotype is homozygous recessive. There is 1 such genotype out of 4 total genotypes in the Punnett - square.

Answer:

$\frac{3}{4}$ of the offspring would have the dominant phenotype, and $\frac{1}{4}$ of the offspring would have the recessive phenotype.
