A plant of genotype Aa; Bb; Cc is fertilized by a plant that is completely dominant for each of the genes. (Assume that A, B, and C are dominant to a, b, c and that the three genes assort independently). What proportion of the offspring will have the same phenotype as the heteroallelic plant? Use the branch-line method to answer this question.

CC DD and cc dd individuals were crossed to each other, and the F1 generation was backcrossed to the cc dd parent. 903 Cc Dd, 897 cc dd, 98 Cc dd, and 102 cc Dd offspring resulted. 1. How far apart are the c and d loci? 2. What progeny and in what proportions would you expect to result from testcrossing the F1 generation from a CC dd x cc DD cross to cc dd?

Question6 1 pts Recall that, in a type of mouse, fur color is determined by alleles at one gene locus; allele A for brown fur and allele a for white. Height is determined by another gene locus; allele B for tall and allele b for short. Each uppercase allele is completely dominant to their respective lower case allele. The 2 gene loci sort or segregate independently. There are no interactions. Mouse 1 (genotype AaBb) mates with mouse 2 (genotype AaBb)...

Given the genotype AaBbCcDdEE a) How many kinds of gametes can this individual form? b) If selfing occurred, what fraction of the progeny would have the following genotype: AaBBccDdEE? A cross between two plants produces progeny which, through subsequent breeding experiments, are shown to fall into 27 genotypic classes. Assuming that complete dominance operates at all of the loci involved and that each locus has two alleles, a) At how many different loci are the parents heterozygous? b) How many...
