Punnett square
- The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.
- It is a helpful tool that helps to predict the probabilities and variations that can come from cross-breeding that can come from cross-breeding.
- The genotypic ratio describes the number of times a genotype would appear in the offspring after a test cross.
- The phenotypic ratio refers to the relative number of offspring manifesting a particular trait or combination of traits.
Considering parents: RRYY × rryy
F₁ Generation: RrYy
Gametes: RY, Ry, r Y, ry
After the Punnete's square
In F2 generation
The genotypic ratio is: 1:2:1: 2:4:2:1:2:1
The phenotypic ratio: 9:3:3:1
