Question

A cross was made betwen pure breeding pea plants one with round and green seeds and other with wrinkled and yellow seed write phenotype of f1 progeny

Answer 1

(a) The cross was made between round, green seeds and wrinkled, yellow seeds. In the given cross, two traits were taken into account, which is a dihybrid cross. Yellow colour and round shape is dominant over green colour and wrinkled shape. 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

Answer 2

can you please tell me which is dominant and which is resasive
