Let's consider a paternally imprinted gene. A female skink inherited alleles that that confer: 1) a mutant violet tail-color in the egg and 2) a mutant violet tail-color allele in the sperm. A male skink mate inherited a wild-type blue allele from the sperm and a mutant violet allele from the egg. They have 500 offspring. a. What tail color phenotypes do the parent male and parent female skinks have? Briefly explain your reasoning. female = male = b. What fraction of the offspring do you expect to have each phenotype (blue and violet tail color)? Briefly explain your reasoning/show your work.

Question

Transcribed Image Text:**Genetics of Tail Color in Skinks**
Let's consider a *paternally imprinted* gene. A female skink inherited alleles that confer: 1) a mutant violet tail-color in the egg and 2) a mutant violet tail-color allele in the sperm. A male skink mate inherited a wild-type blue allele from the sperm and a mutant violet allele from the egg. They have 500 offspring.
**Questions:**
a. What tail color phenotypes do the parent male and parent female skinks have? Briefly explain your reasoning.
- **female =**
- **male =**
b. What fraction of the offspring do you expect to have *each* phenotype (blue and violet tail color)? Briefly explain your reasoning/show your work.
