Students have asked these similar questions
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?
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
How is this trait inherited?
A.
The trait is epistatic.
B.
The trait is X-linked.
C.
The trait is dominant.
D.
The trait is recessive.
