2. Uniparental disomy is a rare phenomenon in whichonly one of the parents of a child with a recessivedisorder is a carrier for that trait; the other parent ishomozygous normal. By analyzing DNA polymorphisms, it is clear that the child received both mutantalleles from the carrier parent but did not receive anycopy of the gene from the other parent.a. Diagram at least two ways in which uniparentaldisomy could arise. (Hint: These mechanismsall require more than one error in cell division,explaining why uniparental disomy is so rare.)Is there any way to distinguish between thesemechanisms to explain any particular case ofuniparental disomy?

11. What evidence do you see in the pedigree illustrated if any, allowing the mode of inheritance for this trait to be deduced as completely vs. incompletely dominant? Do not consider any other information beyond what is shown in the pedigree. Answer in one complete sentence, referring to any individuals in the pedigree who may be informative using generation and individual numbers.

4. An albino corn snake is crossed with a normal-coloredcorn snake. The offspring are all normal-colored.When these first-generation progeny snakes arecrossed among themselves, they produce 32 normalcolored snakes and 10 albino snakes.a. How do you know that only a single gene is responsible for the color differences between these snakes? b. Which of these phenotypes is controlled by thedominant allele?c. A normal-colored female snake is involved in atestcross. This cross produces 10 normal-coloredand 11 albino offspring. What are the genotypes ofthe parents and the offspring?
The following pedigree shows the pattern of inheritance of red green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in red. What is the chance that a son of the third-generation female indicated by the arrow will be color-blind if the father is a normal man? If the father is color-blind?
Clubfoot is a common congenital birth defect. This defect is caused by a number of genes but appears to be phenotypically distributed in a noncontinuous fashion. Geneticists use the threshold model to explain the occurrence of this defect. Explain this model. Explain predisposition to the defect in an individual who has a genotypic liability above the threshold versus an individual who has a liability below the threshold.

The following pedigree shows the pattern of inheritance of this trait in one family: From the pedigree, can you tell if polydactyly comes from a dominant or recessive allele? Is the trait sex-linked?
