Question

In pea plants, yellow seed is dominant over green seed. Construct a Punnett Square for the cross between a he)¿terozygous and a hom)=ozygous recessive (for this trait) Show all of the steps according to the instructions you have been given. Give the genotype and phenotype ratios resulting PLEASE HELP

Answer 1

Answer:

genotype: 50% Yy 50% yy

phenotype: 50% yellow and 50% green

Explanation:

simply make a punnett square and cross the heter0zygous (Yy) and hom0zygous recessive (yy) between each other to get the genotypical results of Yy, yy, Yy, and yy. the phenotypical results are based on which color is dominant over which so Yy would be considered the dominant trait and that is yellow and yy is recessive and green. because you have two of each it is a 50% chance the pea plants offspring will be green and a 50% chance it will be yellow.
