Patterns of Inheritance

Different types of _______ inheritance patterns include incomplete dominance, co-dominance, multiple alleles, polygenic, and sex-linked.

• Non-Mendelian

• Mendelian

The alleles of a gene pair in a heterozygote are both expressed with no blending.

• codominance

• incomplete dominance

• polygenic

• multiple alleles

NGSS.HS-LS3-2

A trait associated with a gene that is carried on the X or Y chromosome.

• sex linked

• polygenic

• multiple alleles

• codomiance

Tags

NGSS.HS-LS3-1

Trait determined by more than one gene, sometimes hundreds of genes.

• polygenic

• multiple alleles

• codominant

• sex linked

Neither allele is dominant. Heterozygote has a blended phenotype.

• incomplete dominance

• codominance

• multiple alleles

• sex linked

Three or more alternative forms of a gene that can occupy the same locus.

• multiple alleles

• codominant

• polygenic

• incomplete dominance
