NEET BIOLOGY

Detailed explanation-1: -A Punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes. A Punnett square can be used to determine a missing genotype based on the other genotypes involved in a cross.

Detailed explanation-2: -A Punnett Square is a helpful tool that helps to predict the variations and probabilities that can come from cross breeding. This includes predicting crossing plants, animals, even humans with each other.

Detailed explanation-3: -A Punnett Square (so named after it’s creator, Reginald C. Punnett) is a chart drawn to determine the probable results of a genetic cross. It will show you every possible combination of offspring that result from a cross. Therefore, a Punnett square is a prediction that estimates what we should see in nature.

Detailed explanation-4: -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-5: -Punnet squares are used to predict the genotypes and phenotypes of offspring using known dominant and recessive genes for single gene traits. The genotype for one parent is written along the side of the square with dominant alleles written as capital letters and recessive alleles written as lowercase letters.
