Free math problem solver answers your homework questions with step-by-step explanations. A phenotype ratio of 9:3:3:1 in the offspring of a mating of two organisms heterozygous for two traits is expected when: Tutorial A. the genes reside on the same chromosome Genes on the same chromosome might be linked. If we assume linked genes, and that the heterozygotes are F1-hybrids from true breeding parents, the offspring would be Integration. ∫ 01 xe−x2dx. Limits. x→−3lim x2 + 2x − 3x2 − 9.

This is the ratio of phenotypes in a dihybrid cross. If both parents are heterogeneous for both traits the ratio of phenotypes is the ratio of 9:3:3:1. One trait is dominant and the other trait is recessive. Of the 16 possible offsprings only 1 will have both recessive genes. Only with double recessives will the phenotype show both recessives. Nine will have at least one gene for both dominate The hypothesis that color and shape genes assort independently thus predicts that the F2 generation will display a 9:3:3:1 phenotypic ratio: nine individuals with round, yellow seeds, three with round, green seeds, three with wrinkled, yellow seeds, and one with wrinkled, green seeds.
