Pedigrees are often used in humans to examine the transmission patterns of genetic diseases. They can be used to determine if a disease is autosomal dominant, autosomal recessive, X-linked recessive, or X-linked dominant. The pedigree below shows inheritance of Huntington's Disease, a rare disorder which destroys nerve cells of the brain.

(A) Which type of inheritance does Huntington's Disease follow? How did you make this determination?

(B) What is the genotype of individual II-6?

(C) What is the genotype of individual III-2?

Gillespie syndrome (GS) is a rare genetic disorder. The disorder is characterized by having part of the iris missing, ataxia, and, in most cases, intellectual disability. It is termed as a heterogenous disorder because it can be inherited either through an autosomal dominant pattern or through an autosomal recessive pattern. Two parents are heterozygous for GS. A. Assuming that the condition is following an autosomal dominant pattern, what are the ratios or percentages of the genotypes AND phenotypes for the...

"The orange locus in cats is located on the X chromosome. In females, XoXo results in orange cats and X+X+ results in black cats When a female is heterozygous XoX+, they express both colors in patches due to a phenomenon called X-inactivation in which one X in every cell is inactivated. These females are called calico or tortoiseshell, depending on the presence of white spots. Male cats are either orange (XoY) or black (X+Y). A cross between a black female...
