Every somatic cell in a human contains 23 pairs of chromosomes. Pairs 1 to 22 are autosomes, while pair 23 are the sex chromosomes. The pairs are described as homologous chromosomes. Answer the following questions about homologous chromosomes: Where do the chromosomes that make up each pair come from? Explain how the terms homologous chromosomes and sister chromatids are different. In genetic males, there is one pair that is not homologous. Identify the pair and explain why.
While working in the lab, you notice that your fruit flies all appear to have an intersex phenotype. This is most likely due to: O There being a 2:3 ratio of X chromosomes to autosomal chromosomes. O There being a 1:2 ratio of X chromosomes to autosomal chromosomes. O There being a 3:2 ratio of X chromosomes to autosomal chromosomes. O There being a 1:1 ratio of X chromosomes to autosomal chromosomes. O There being a 1:2 ratio of Y chromosomes to autosomal chromosomes.

An abnormality of the large intestine called intestinal polyposis (IP) is dependent on dominant gene A. A nervous disorder called Huntington’s chorea (HC) is determined by dominant gene H, a lethal gene the effects of which appear on a mean age of 40 years. A and H are on nonhomologous chromosomes. A man carrying the gene A marries a woman carrying the gene H. If this couple had 7 children, what is the chance that at least 2 of their children will survive up to old age? What are the genotypes of the man and his wife?
