Question

A cross was made between pure breeding pea plants, one with round and green seeds and the other with wrinkled and yellow seed.
A. Write the phenotype of F1 progeny. Give reasons for your answer
B. Write the differeobtained along with their ratio F1 progeny

Answer 1

in F1 we get round and green seeds ( heterozygous)
in f2 u will get round and green to wrinkled and yellow seeds are 3:1

Answer 2

In F1=3:1
because this follows the law of dominance in which the yellow character dominates the green colour of the pea plant..
The difference is that the all plants will be yellow and round except 1 i.e.green wrinkled.
