Answer 1

Question:

Solution:

To estimate the genotypic and phenotypic ratio, calculate the number of Punnett squares with each allele combination. So, in this example, we get the following punnet square:

The genotypic ratio for monohybrid cross: 1:2:1 ratio

The phenotypic ratio would be 3:1 ratio.
