Principles of Inheritance and Variation question

2021 · Q4

NEETBiologyPrinciples of Inheritance and VariationMCQ+4 / −1
The production of gametes by the parents, formation of zygotes, the F1 and F2 plants, can be understood from a diagram called :
  1. A
    Net square
  2. B
    Bullet square
  3. C
    Punch square
  4. D
    Punnett square
View written solutionFree

Correct answer: D

Punnett square is a tool that helps to show all possible allelic combinations of gametes in a cross of parents with known genotypes in order to predict the probability of their offspring possessing certain sets of alleles. For a cross involving two genes, a Punnett square is still a good strategy.
