Name: __________________________ Date: _____________ 1. In hogs, a dominant allele B results in a white belt around the body. At a separate unlinked locus the dominant allele S causes fusion of the two parts of the normally cloven hoof resulting in a condition known as syndactyly. A belted syndactylous sow was crossed to an unbelted cloven-hoofed boar, and in the litter there were: 25% belted syndactylous 25% belted cloven 25% unbelted syndactylous 25% unbelted cloven What are the genotypes of the parents? A) B/B ; S/S x b/b ; s/s B) B/b ; S/s x b/b ; S/S C) B/b ; S/s x B/B ; s/s D) b/b ; S/s x B/b ; s/s E) B/b ; S/s x b/b ; s/s 2. In the cross between A/a ; B/b ; C/ c; D/d ; E/e and a/a ; B/b ; C/C ; d/d ; E/E , what proportion of the progeny will show the dominant phenotype at each locus? (Assume independent assortment of all genes and complete dominance.) A) 1/32 B) 1/16 C) 3/8 D) 9/16 E) 3/16 Page 1

3. Below is a pedigree of a human genetic disease in which stricken individuals are solid-colored. Apply the laws of probability and calculate the probability the offspring of the cousin marriage 1x 4 will have the disease . 4. The following pedigree shows the inheritance of attached earlobes (black) and unattached earlobes (white). Both alternative phenotypes are quite common in human populations. If the phenotypes are determined by alleles of one gene, then attached earlobes are inherited as a(n).. 5. 0 A couple has a female child with Tay Sachs disease, and three unaffected children. Neither parent nor any of the four biological grandparents of the affected child has had the disease. The most likely genetic explanation is that Tay Sachs disease is inherited as a(n) … Page 2

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
