NGSS.HS-LS3-2

The heterozygotes resulting in a cross between two purebreds has a phenotype that resembles an intermediate form between the two parents. 

• Incomplete Dominance

• Complete dominance

• Co - Dominance 

• Multiple Alleles

The Himalayan Chinchilla can be different varieties of colors based on inheriting combinations of the  C allele, C^ch , or C^h allele

• Polygenic Inheritance

• Pleiotropy

• Codominance 

• Multiple Alleles

NGSS.HS-LS3-2

A person with blood type AB expresses two markers on the surface of their blood cells. Each marker is coded for by a different allele. 

• Complete dominance

• Multiple Alleles

• Codominance 

• Polygenic Inheritance

In a cross between a round(R)-yellow(Y) seeded plant and a wrinkled (r)- yellow(Y) seeded pea plant, green(y)-wrinkled (r) seeded offspring are produced.

a. What are the genotypes of parents?

• RrYy X rrYy

• RrYY X rrYy

• RrYy X RrYy

• RRYy X rrYy

• RRYy X RrYY
