In some horses, coat color is autosomal and exhibits incomplete dominance, with palamino coloration intermediate to both chestnut and cremello coloration. Horses can also exhibit an immunodeficiency syndrome inherited as an X-linked recessive allele. You are a horse breeder, and cross a palamino female carrier for immunodeficiency syndrome with a normal, cremello male.
1. Use appropriate genetic notation to describe genotypes of the cross.
2. If you conducted this cross many times, what would be the expected phenotypic offspring ratio? Be sure to identify which genotype is associated to each phenotype, and differentiate between male and female offspring.
3. What is the probability of obtaining offspring that both breed true for coat color AND does not possess the immunodeficiency allele?
