Genetic diagrams of crosses Heredity Mendelian inheritance Squares shape. This page was last edited on 30 Novemberat Adding more traits increases the size of the Punett Square. With one row or column for each allele combination, the total number of boxes in a Punnett Square equals the number of rows times the number of columns.

Hardy—Weinberg law – Punnett square. If one of the parents is a homozygote for one or more traits, the Punnett Square still contains the same number of boxes, but the total number of unique allele combinations is 2 raised to the power of the number of traits for which the parent is heterozygous.

Complete the genotypes in the square by filling it in with the alleles from each parent. A simpler pattern arises when one of the parents is homozygous for all traits. Since only females were used for egg-production, early identification of male chicks, which were destroyed or separated for fattening, meant that limited animal-feed and other resources could be used more efficiently.
