NGSS.HS-LS4-3

When the heterozygous genotype results in a phenotype where both alleles are fully and separately expressed.

• Heterozygous

• Codominance

• Incomplete Dominance

• Multiple Alleles

Chromosomes 1-44 in a human.

• Sex Chromosomes

• Autosomes

• Epistasis

NGSS.HS-LS3-1

Only expressed in the homozygous state.

• Dominant

• Recessive

• Genotype

• Phenotype

Genes travel on the X chromosome.

• Multiple alleles

• Codominance

• Sex-Linked genes

• Allele

Chromosomes line up randomly during metaphase therefore it is possible for any combination of chromosomes to be passed on from parent to offspring.

• Law of Dominance

• Law of Segregation

• Law of Independent Assortment

• Polygenic Inherit
