NGSS.HS-LS4-3

A cross of two different genes (ex: hair color and eye color)

• Dihybrid cross

• Incomplete dominance

• codominance

• Polygenic traits

One allele does not express dominance over the other (Traits will mix to form third new trait)

• Dihybrid cross

• Incomplete dominance

• codominance

• Polygenic traits

Both alleles contribute to the phenotype (Traits will show themselves simultaneously and separately – blood type AB)

• Dihybrid cross

• Incomplete dominance

• codominance

• Polygenic traits

Traits controlled by 2 or more genes – eye color

• Dihybrid cross

• Incomplete dominance

• codominance

• Polygenic traits

The passing of traits from one generation to its offspring

• Heredity

• Traits

• Genes

• Alleles
