Incomplete Dominance
Inheritance pattern where the phenotype of a heterozygote is intermediate between those of the two homozygotes neither allele of the pair is dominate but combine and display a new trait.
Codominant allele
pattern where phenotypes of both homozygotes parents are produced in heterozygous offspring so that both alleles are equally expressed.
Multiple alleles
presence of more that two for a genetic trait.
Autosome
pairs of maching homologous chromosomes in the somatic cells.
sex chromosomes
i humans, the 23rd pair of chromosomes determine the sex of an individual.
sex-linked trait
