Question

question 2
which is an example of codominance?
a a homozygous black and homozygous white cow mate and produce a gray calf.
b a homozygous black and homozygous white cow mate and produce three black calves and one white calf.
c a homozygous black and homozygous white cow mate and produce three white calves and one black calf.
d a homozygous black and homozygous white cow mate and produce a black and white spotted cow.

Explanation:

Codominance is a type of inheritance where both alleles in a heterozygous individual are fully expressed. In the case of the black - and - white spotted cow, both the black and white alleles are visibly expressed simultaneously. In option A, it is incomplete dominance as the offspring shows an intermediate phenotype (gray). Options B and C follow simple Mendelian inheritance patterns with one allele being dominant over the other.

Answer:

D. A homozygous black and homozygous white cow mate and produce a black and white spotted cow.
