A ___ square is a diagram used to predict all possible allele combinations from a genetic using this diagram, the phenotype's of offspring can be determined from the genotypes .

A punnett square is a diagram used to predict all possible allele combinations from a genetic cross (recombination). Using this diagram, the phenotypes of offspring can be determined from the genotypes.

Explanation:

A punnet square can be described as a diagram which illustrates all the possible outcomes of a genetic cross. This diagram tells the probability of particular genotypes and phenotypes of the offsprings.

A punnet square is made by crossing the particular alleles of the female parent with the particular alleles of the same genes of the male parent. The result will depict the possibilities for the genotypes and phenotype of offsprings. This square can also help in depicting the carriers as well as the diseased offsprings for a particular inherited disease. :)
