Final answer:
A Punnett square is a chart that allows you to easily determine the expected percentage of different genotypes in the offspring of two parents. It is derived from the laws of probability and is used to predict the possible offspring from a cross or mating between two parents. Punnett squares are particularly useful in genetics to study the inheritance of traits and understand how factors are passed on from generation to generation.
Step-by-step explanation:
A Punnett square is a chart that allows you to easily determine the expected percentage of different genotypes in the offspring of two parents. It is derived from the laws of probability and is used to predict the possible offspring from a cross or mating between two parents. In a Punnett square, the possible offspring are represented by the letters in the boxes, with one factor coming from each parent. By filling in the squares with the correct alleles, you can determine the genotypes and predict the percentages of different phenotypes in the offspring. Punnett squares are particularly useful in genetics to study the inheritance of traits and understand how factors are passed on from generation to generation.
