Located on the x chromosome of a cat is a gene that codes for deafness. This gene is recessive. A female cat that is heterozygous for deafness is crossed with a male cat that is not deaf. What are the genotypes and phenotypes of the offspring?
Genotypes:
Phenotypes:
This gene is an X linked recessive trait, thus for it to be expressed in the females, it has to be in the homozygous recessive form (both X chromosomes will carry this trait dd). For males, only one copy which is in the recessive condition is needed for it to be expressed. Thus, a cross between

The T-chart by categorizing each statement as something that would most likely be relevant to gene flow or genetic drift. Some answers will fit in both columns depending on the situation. is random is a mechanism for evolution is often related to disasters is also called “migration” deals with movement between populations...
