Detailed explanation-1: -The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given. In its simplest form, the Punnett square consists of a square divided into four quadrants.

Detailed explanation-2: -The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.

Detailed explanation-3: -A Punnet square shows the genes (represented by letters) in the parents’ gametes along the top and left-hand side of a square and the possible gene combinations in the offspring, within the square. A completed Punnett square gives the probable outcome of a given cross.

Detailed explanation-4: -To construct a Punnett square, the genotypes of both parents must be known. One parent’s alleles are listed across the top of the table, and the other parent’s alleles are listed down the left hand side. The resulting offspring genotypes are produced at the intersection of the parent’s alleles.

Detailed explanation-5: -Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. It shows the genotypes two individuals can produce when crossed. A genotype is the genetic makeup of the organism. The phenotype is the trait those genes express.
