Sex-linked trait inheritance
Genes that are located on the sex chromosomes are called sex-linked traits Examples –Baldness and colorblindness

Incomplete Dominance Incomplete dominance is when the heterozygous phenotype is somewhere between the two homozygous phenotypes
5
Codominance Codominance is when both alleles of a gene are expressed completely- neither allele is dominant nor recessive
6
Polygenic Traits Polygenic traits- traits produced by two or more genes
