In horses, horses can be black (B) or red (b). If a horse with genotype Bb has the same phenotype as a horse with genotype BB, coat color exhibits this type of dominance
What is complete dominance?

One trait is controlled by many genes
What is a polygenic trait?

The building block of a nucleic acid.
What is a nucleotide?

How many molecules of DNA are present after one round of replication

Horses can have the gene for black (B) or red (b). A modifier gene that codes for grey color (G) is epistatic over both colors. If a horse was born red but grayed with age, this would be his genotype if only one of his parents were grey
What is bbGg?

In humans, "brown-eyed girls" are highly desired. Brown eyes (B) are completely dominant over blue eyes (b). If a blue eyed man and a woman who is a carrier for blue eyes had a child, this is the probability of the couple having a brown-eyed girl.

In beef cattle, large bone size (B) is a desirable trait and is dominant over thin bones (b). However, their milk production is weak compared to dairy cattle. High milk production (m) is a recessive trait. If a beef bull that is heterozygous for bone size and homozygous dominant for milk production is bred with a dairy cow with thin bones and high milk production, these are the combinations of alleles that EACH will pass in their gametes.
What are... - bull: BM, bM - cow: bm

In roses, we will evaluate 3 completely dominant traits: - Color: Red (R) or white (r) - Thorns: Thorny (T) or smooth (t) - Stems: Long (L) or short (l) This is the probability of getting a white, thorny, long-stemmed rose if the parents' genotypes are RrTTll and rrTtLL
