Certain individuals in this family are affected by a brain condition that makes them more susceptible to vertigo. As a genetic counselor, you interview the family and draw DNA samples. You discover that the condition is caused by a mutation that changes the sequence 5’GCATTC3’ to 5’GAATTC3’ introducing an EcoRI cut site. You decide to amplify a 1200bp fragment from the DNA that spans this mutation and then digest it with EcoRI. You run the results on a gel next to a marker that shows bands at 2000bp, 1200bp, 900bp, 800bp, and 400bp. Some individuals from the pedigree are identified on the gel.arrow_forward

Explain the type of transmission for the type of albinism depicted in this family. What does the pedigree tell you about the individual labeled Y's genotype? There are two genes known to cause this type of albinism found in this family: OCA1 and OCA2. If we know 1 (albino great grandmother) had mutation in OCA1 which gene would you hypothesize is mutated in individual Y's genome? Explain your reasoning. generations Key: D ở abino Ped.
