Please show WORK!

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?

In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth and are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov. The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there...

Suppose you have a group of beetles. You find that a white eye color in one of the beetles is due to a point mutation. Refer to B and b (where B is the allele associated with the dominant phenotype, and b is the allele associated with the recessive phenotype) in order to answer the following questions: 1) The cross of a pure breeding male with white eyes with a pure breeding female with normal eyes leads to all offspring...

Simple Dominance with 2 genes A gene in cats causes them to be black (dominant) or brown (recessive). A second gene causes cats to be agouti (have stripes on their hairs) or non-agouti (solid colored hairs). If you did a dihybrid cross between two black haired agouti cats, what fraction of the offspring would be expected to have each phenotype? If a dihybrid black agouti cat mated with a brown cat that was heterozygous for the agouti gene, what fraction...
