In humans, hair type follows the rules of incomplete dominance. When babies are heterozygous, they have wavy hair.

If a father with wavy hair (CS) and a mother with straight hair (SS) have a baby, what chance does the baby have to get wavy hair (CS)?

Andalusian chickens have one allele for black feathers (B) and one allele for white feathers (W). Andalusian chickens appear to have black and white checkered feathers (BW), whereas homozygous chickens are either black (BB) or white (WW).

An Andalusian rooster and an Andalusian hen are crossed. Complete the sentences below for the predicted outcome of offsprings produced.

The Andalusian rooster genotype is .

When these two chickens are crossed, will be Black, and

A specific type of retrievers can have a black coat color, a white coat color, or a grey coat color.

A black retriever has a genotype of RBRB while a white retriever has a genotype of RWRW. However when the retriever is heterozygous for gray it will have a genotype of RBRW.

When a male black retriever dog mates with a female heterozygous gray dog, what is the expected ratio of the resulting offspring?
