A 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 ...This worksheet is perfect for times when your students need the repetition required for the learning how to quickly fill out a Punnett square.

Heterozygous or hybrid in the color gene and also heterozygous in the shape gene. And so that's why this is called a dihybrid cross. You're crossing things that are hybrid in two different genes. Now, we've already talked about the law of segregation. The gamete is randomly going to get one copy of each gene.Punnett square; Monohybrid cross; Gene; Allele Dominant alleles; Recessive alleles; Homozygous; Heterozygous; A Punnett square is a grid formed by 4 squares to form a larger square.
