Textbook Question
Chapter 9, Problem 4SQ
Whether an allele is dominant or recessive depends on
- a. how common the allele is relative to other alleles.
- b. whether it is inherited from the mother or the father.
- c. whether it or another allele determines the
phenotype when both are present. - d. whether or not it is linked to other genes.

A cross between a horse homozygous for red hair and a horse homozygous for white hair results in offspring with the coat colour called roan. When you look at the fur of the roan offspring you see both red and white hairs. What type of inheritance best explains this?
a) blending inheritance
b)codominance
c)incomplete codominance
d)multiple alleles
a. Why males and females do not show equal chances of inheriting a trait?
b. Is it possible to determine the genotypes of the parents based on the phenotypes of the offspring?

The trait is epistatic.
B.
The trait is X-linked.
C.
The trait is dominant.
