Assume that the ability to curl your tongue up on the sides (T, taco tongue rolling) is dominant to the recessive “t” allele (not being able to roll your tongue).  A homozygous dominant woman marries a man who cannot roll his tongue. What are the chances that their child will have the same phenotype as their mother?

Brachydactyly type D is human autosomal dominant condition in which the thumbs are abnormally short and broad. In most cases, both thumbs are affected, but occasionally just one thumb is involved. The pedigree above shows a family in which brachydactlyly type D is segregating. Filled circles and squares represent females and males who have involvement of both thumbs. Half-filled in symbols represent family members with just one thumb affected. There is evidence of variable expressivity and incomplete penetrance in this family. Name 3 individuals who are nonpenetrant for the trait? (eg. IV 7)

In ____________, homozygosity for the recessive allele at one locus will mask the phenotypic expression of the alleles at a second locus. This leads to a 9:3:4 genotypic ratio. The relationship is shown in the figure below

Genes A and B are located 10 cM from each other on a chromosome. Gene C is located 25 cM from gene A and 15 cM from gene B. What is the probability that the trihybrid ABC/abc will produce a double recombinant gamete?

A fly that is heterozygous at three loci is testcrossed to a fly with black eyes, bent wings, and hairy legs. The 1000 offspring shown below are obtained from this cross: red eyed, straight winged, smooth legged                 8 black eyed, bent winged, hairy legged                       12 black eyed, straight winged, smooth legged             39 red eyed, bent winged, hairy legged                           41 red eyed, bent winged, smooth legged                       354 black eyed, straight winged, hairy legged                  366 red eyed, straight winged, hairy legged                      93 black eyed, bent winged, smooth legged                    87   (1) What is the phenotype of a fly that is heterozygous at all three loci? (2) “Draw” a genetic map of these three loci

In fruit flies, the red eye allele (pr+) is dominant to the purple eye allele (pr) and the normal wings allele (vg+) is dominant to vestigial wing allele (vg). These loci are located on the same chromosome. A pure breeding red-eyed fly with vestigial wings was crossed with a pure-breeding purple-eyed fly with normal wings. All of the F1 progeny had a WT phenotype. Which of the following represents the arrangement of alleles on the F1’s chromosome?
