In a cross between a yellow and a green speeded pea plants all `F_(1)` members are yellow But `F_(2)` generation riased by crossing two such `F_(1)` consists of approximately `75%` yellow and `25%` green seeded pea plants.
(i) What will be the offspring be like two `F` greens are mated?
(ii) What will be the genotypic ratio in the population of yellow seeded plants in `F_(2)` generation ?

Explanation

It is monohybrid cross.

(i) `overset(yy xx yy)underset(yy)(darr)` i.e., All green-seeded pea plants are obtained.
(ii) Genotypes of yellow - seeded pea plants `:.` genotypic ratio `= 1 : 2`
