a. What is the Raly gene? What does it encode? How does it relate to the lethality of Ay? b.  A heterozygous mouse AAy does not produce enough pigment and it is yellow. Homozygous individuals die during development, but AAy heterozygous do not. Why? You may use any graphic aid to explain this, if necessary. This means that you may use a Punnett square or a forking segregation diagram, or computations with fractions. c. Explain why there is a non-Mendelian 2:1 yellow/agouti phenotypic ratio in this cross.
A. Deletion of the SOX9 gene leads to sex reversal resulting in a person with karyotype 46XY being phenotypically    Explain the genetic basis for this.    B. Describe what would happen to the phenotype of a male with a mutation in the gene encoding SF1? Explain your answer.
A normal appearing female infant was identified with a positive newborn screen, linked to chromosome 12. Few years ago, her older sibling had developed profound hypoglycemia, liver failure leading to coma, and subsequent irreparable brain damage, following a viral illness. The sibling was subsequently shown by clinical testing to have the same disorder that this female infant is screened positive for. a. What is the most likely diagnosis? b. What biomarkers would confirm this on the newborn screening process? Describe the mechanism that causes this metabolic defect.
