Dominant traits- In genetics, a trait that will appear in the offspring if one of the parents contributes it.
Recessive traits-can be carried in a person's genes without appearing in that person. For example, a dark-haired person may have one gene for dark hair, which is a dominant trait, and one gene for light hair, which is recessive.
Phenotype-an obvious and observable trait; it is the expression of genes in an observable way. An example of a phenotypic trait is hair color, there are underlying genes that control the hair color, which make up the genotype,
Genotype-the genetic makeup of an organism or group of organisms with reference to a single trait, set of traits, or an entire complex of traits.
