Question

Imagine you are performing a cross involving seed color in garden pea plants. What F1 offspring would you expect if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green.

Answer 1

Answer:

Yy, Yy, Yy, Yy

Yellow in color

Explanation:

Let the allele for green seed be represented by "y" and the allele for yellow seed be represented by "Y"

Given Yellow seed color is dominant over green.

Genotype of  true breeding green seed parents will be yy

Genotype of  true breeding yellow seed parents will be YY

F1 cross

$YY * yy\\Yy, Yy, Yy, Yy$

Genotype of all the offspring is heterozygous "Yy"

Phenotype of all the offspring is yellow
