In humans the ability to taste Phenylthiocarbamide (PTC) is dominant. “Tasters” (TT) or (Tt) taste an extremely bitter taste from PTC, while “non-tasters” (tt) do not taste anything.

What are the genotypes of Mr. and Mrs. Jones if they can taste PTC but have a child who is a non-taster?

In pigs, having erect ears that stick up (E) is dominant to having droopy ears (e).

If a pig has droopy ears what must its genotype be?

Draggable item		Corresponding Item
Genotype		the form of a gene that can mask the other
Homozygous		the form of a gene that can be covered up when present with another form
Phenotype		the way an organism looks
Heterozygous		the genetic make up of an individual
Dominant		having two of the SAME version of a gene (dominant or recessive)
Recessive		having two DIFFERENT versions of a gene

In horses, having black hair is dominant (B) to having chesnut colored hair (b).

If a homozygous dominant horse is crossed with a chesnut colored horse, then what are the chances they will have a foal (a baby horse) with chesnut colored hair?
