Question

allele and a recessive allele are inherited. the offspring will have a _____________ of these two alleles. for example, in some species of ___________, gray fleece results from a dominant ___________-fleece allele and a recessive ___________ allele. incomplete dominance also occurs in ___________ color in some species of _____________.
codominance
unlike _____________ dominance, which shows blending of traits, ___________ results in ___________ alleles being expressed at the same time. in cattle, horses, and ___________, there is a color pattern called _____________ which appears when a dominant white-hair allele and a dominant solid-color allele is inherited.

Explanation:

This content covers incomplete dominance and codominance, key genetic inheritance patterns. The blanks are filled based on standard biology genetics examples and definitions:

1. Offspring inherit a pair of alleles (one dominant, one recessive) in incomplete dominance, leading to a blended trait. Sheep are a classic example where gray fleece comes from white (dominant) and black (recessive) fleece alleles. Flower color in plants (like snapdragons) is another common incomplete dominance example.
2. Codominance differs from incomplete dominance as both dominant alleles are fully expressed simultaneously. Roan color in cattle, horses, and goats results from dominant white and solid-color alleles being expressed together.

Answer:

allele and a recessive allele are inherited. The offspring will have a blended combination of these two alleles. For example, in some species of sheep, gray fleece results from a dominant white-fleece allele and a recessive black allele. Incomplete dominance also occurs in flower color in some species of plants (e.g., snapdragons).
Codominance
Unlike incomplete dominance, which shows blending of traits, codominance results in both dominant alleles being expressed at the same time. In cattle, horses, and goats, there is a color pattern called roan which appears when a dominant white-hair allele and a dominant solid-color allele is inherited.
