What do the letters in each box of of punnett square tell you?

a. the parents of a set of offspring

b. the possible combinations of alleles is offspring based on the parents genetic makeup

c. that both parents show characteristics of dominant trait

d. how to assemble a genetic map of the chromosome on which alleles are located

The correct answer is B) The possible combinations of alleles in offspring is based on the parents genetic makeup .

Punnett square is a square diagram that depicts genotypes of the offsprings that are produced by cross between two parents.

It has the gametes produced by parents on the outer side and combinations of alleles in the offsprings in each box of the punnett square.

Thus, B) is the right answer.

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.
