Question

Give a genetic explanation for the following cross (a) When a tall pea plant with round seeds was crossed woth wrinkled seeds then all the f1 progenies are same (b) find out the phenotypic ratio of f2 generation

Answer 1

Answer:

It is a dihybid cross i.e to characters are taken .In F1generation all are hybrid tall and round seeds.In F2 generation phenotypic ratio is 9:3:3:1 and genotypic ratio is 1:2:2:4:1:2:1:2:1 or very complex

Explanation:

Here R is dominant round and r is recessive wrinkle

T is dominant tall and t is recessive drawf
