Phenotypic and genotypic ratio are equal in
WebA two-trait Punnett Square has 16 boxes. The probability of a cross producing a genotype in any box is 1 in 16. If the same genotype is present in two boxes, its probability of occurring doubles to 1/8 (1/16 + 1/16). 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 ... WebMar 26, 2024 · The genotypic ratio for this cross is written 1:2:1. In animals and plants, each gene has 2 alleles or variations, one from each parent. When male and female gametes …
