2. While working as a doctor at Harbor UCLA Hospital, you come across a young girl who has a rare genetic disorder due to a recessive mutation in a gene called XF5. Both the girl's parents are healthy. You take a cheek swab from the girl and her parents, extract DNA from their cheek cells, and sequence their genomes. a. What alleles do you expect to see at gene XF5 when you sequence girl's genome? (2pts) b. What alleles do you expect to find when you sequence their genomes? (2pts) 3. Your friend from medical school is treating a young boy in New York City who has the same genetic disorder as your patient in LA. She takes a cheek swab from the boy and his parents, extracts DNA from their cheek cells, and sequences their genomes. She finds that the boy carries two mutant alleles in XF5, as expected. The mother is heterozygous, and the father has two wild-type alleles. She asks you for help understanding this. How can you explain that the father gavetthe child a mutant allele when he only has wildtype alleles? (4pts) In previous classes, you have learned about the evolution of the black and speckled forms of the peppered moth. A recent study found the genetic bassis of this trait; a mutation increases gene expression of cortex-increased gene expression of cortex results in an increased amount of black color. The wildtype moth is speckled (pictured on the left), and muant moth is black (right). Let's call the wildtype allele " \( r+ \) " and the mutated allele "r-". (21 pts total) a. Is the \( r \) - allele an example of a gof or lof mutation? Why? (4pts) b. What are the three possible genotypes for the cortex gene for these two alleles? (3pts) Indicate which is homozygous wildtype, heterozygous, and
