"WebIn other words, the genotypic ratio (the ratio of expected numbers of genotypes for the cross) predicted for the F2 generation is 1:2:1 for TT:Tt:tt. The tall allele is dominant to the short allele, so F2 plants that are TT or Tt will be tall, and only F2 plants that are tt will be short. So, the Punnett square predicts that for every three ...

WebDihybrid cross is a cross between two individuals with two observed traits that are controlled by two distinct genes.
