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

Explanation:

(a) F1 progeny: Round and Yellow seeds. A cross between two pure varieties obtains hybrid progeny exhibiting only dominant phenotype (law of dominance).

(a) F1 progeny: Round and Yellow seeds. A cross between two pure varieties obtains hybrid progeny exhibiting only dominant phenotype (law of dominance).(b) The different types of progeny obtained with the ratio is as follows;

(a) F1 progeny: Round and Yellow seeds. A cross between two pure varieties obtains hybrid progeny exhibiting only dominant phenotype (law of dominance).(b) The different types of progeny obtained with the ratio is as follows; 9 round and yellow : 3  wrinkled and yellow : 3  round and green : 1 wrinkled and green.
