Incomplete Dominance Quiz

What is incomplete dominance?

• When one allele is completely dominant over the other

• When two different alleles blend together to create a new trait

• When both alleles are recessive

• When alleles do not interact with each other

What are alleles? Select all that apply.

• Different types of genes (represented by letters upper case = dominant allele. lower case = recessive allele) that make up a genotype.

• The phenotypes of the genotype.

• An individual inherits 1 from biological mother & 1 from biological father.

• The offspring or F1 generation

In incomplete dominance, what happens when two different alleles mix together?

• One allele becomes completely recessive

• Both alleles blend together to create a new trait

• One allele becomes completely dominant

• The alleles cancel each other out

What does studying incomplete dominance help scientists understand?

• How to control gene expression in organisms like that shown in image above.

• How to eliminate genetic diversity

• How to create new alleles in organisms

• How traits are passed down from one generation to the next; some can skip generations like shown in picture of pedigree.
