Question

What is represented in the boxes of the Punnett square?

(a) Gametes of male parent

(b) Gametes of female parent

(c) Genotype of the offspring produced

(d) Genotype of all possible offsprings

This question was addressed to me in an interview for job.

Question is taken from Inheritance Principles topic in division Principles of Inheritance and Variation of Biology – Class 12

Answer 1

Correct choice is (a) Gametes of male parent

To explain I would say: In the Punnett square, the boxes are filled with the offsprings that can be produced, in principle, from the combinations of gametes of both parents. This can be used to determine the genotypic and phenotypic ratios of the progeny.
