WebThe probability of the homozygote or the heterozygote is 1/4 + 1/2 = 3/4 using the sum rule. The same probability can be obtained in the same way for each of the other genes, so that the probability of a dominant phenotype at A and B and C and D is, using the product rule, equal to 3/4 × 3/4 × 3/4 × 3/4, or 81/256.

WebA cross between two dihybrids (or, equivalently, self-fertilization of a dihybrid) is known as a dihybrid cross.

WebA dihybrid cross, in the form of a Punnett square, is used to show the inheritance of two genes that control different characteristics. In this example, the two characteristics are stem length and flower color. Stem length is controlled by two different alleles: a dominant allele for tall stems (D) and a recessive allele for short stems (d). ...
WebA trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green). The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an ... strippy and bright table runnerWebDihybrid cross. Google Classroom. Problem.
