Letters A and B represent the genotypes of the Parents
Letters C, D, E, and F represent the genotypes of the Offspring.
Explanation:
The punnet square is a square shaped figure or diagram used to anticipate the genotypes of offspring after a certain parental cross. It helps in determining the genotype as well as phenotype of the offspring if we know the genotype of parents.
The figure was devised for the very first time by Reginald C. Punnett and named after him.
The square diagram can also be considered as a summary of parental and offspring alleles.
It is important to understand the homozygosity and heterozygosity before using the punnet square in proper way.
