A cross was made between pure breeding pea plants one with round and green seeds and the other with wrinkled and yellow seeds
(a) Write the phenotype of F1 progeny. Give reason for your answer.
(b) Write the different types of F2 progeny obtained along with their ratio when F1 progeny was selfed
The above cross shows round and yellow seeds in the F1 generation. It occurs because dominant traits (round and yellow) express itself, whereas recessive traits (wrinkled and green) get suppressed.
(b) On selfing of F1 generation
Phenotypic ratio - 9:3:3:1
Round yellow - 9
Round green - 3
Wrinkled yellow - 3
Wrinkled green - 1
