Q. The graphical representation to calculate the probability of all possible genotypes of offsprings in a genetic cross was developed by

KEAMKEAM 2014Principles of Inheritance and Variation

Solution:

Reginald C. Punnett developed Punnett’s square where all possible gametes of one parent are placed vertically on the checker board and those of other parent are placed horizontally. Then their combinations are worked out. This graphical representation helps to calculate the probability of all possible genotypes of offsprings in a genetic cross.
