Question

A cross was made between pure breeding plants differing in
two characters (colour and shape of seed) and the progenies
were inter-crossed to produce F2 population. Four types of
phenotypes; yellow round (1110), yellow wrinkled (380),
green round (360) and green wrinkled (150) were observed in
F2. Find out the pattern of inheritance this character is

Answer 1
