Question

Crosses between white-coated cattle (Cw Cw) and re coated cattle (Cr Cr0 produce roan offspring (Cr Cw). This type of inheritance pattern is know as

a)s*x linkage

b) codominance

c)crossing over

d)multiple allele inheritance

Answer 1

b) codominance

Both alleles are dominant leading to a mixture of the roan color

Answer 2

w,w   vs   r,r  produce w,r

Co-dominance - neither gene is completely expressed so the cow isnt red or white - its partway between - roan.

Answer 3

b

In codominance, neither phenotype is recessive. Instead, the heterozygous individual expresses both phenotypes.
