Question

A plant bearing yellow seeds Homozygous is crossed with a plant bearing green seeds. What is the phenotype and genotype of F1 and F2 generation

Answer 1

Answer: In F1 plants, all pods will appear green.

In F2, pods will appear in 3:1 ratio, three green and one yellow i.e. in F2, 75% of the pods will be green.

Explanation:

All plants of F1 generation will be hybrid, and will express dominant pod colour which is green.

In the F2 generation of the cross, three will be green and one will be yellow. It is due to dominant and recessive gene combinations.

Out of three green, one will be pure and remaining two of hybrid type. The yellow will be pure combination of recessive genes.
