Incomplete Dominance Practice

Front

What is incomplete dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a phenotype that is a blend of the two traits.

What is the genotype for a brown mouse in an incomplete dominance scenario where black (BB) and white (bb) are homozygous?

Back

Bb

In a cross between a tall plant (TT) and a medium plant (TS), what fraction of the offspring will be tall?

Back

Front

What phenotype does the heterozygous genotype (Dd) express in a cross involving straight hair (D) and curly hair (d) in dogs?

Back

Wavy hair.

Front

What is the phenotype of a homozygous dominant genotype in incomplete dominance?

Back

The phenotype will express the dominant trait fully.

Front

What is the phenotype of a homozygous recessive genotype in incomplete dominance?

Back

The phenotype will express the recessive trait fully.

Front

In incomplete dominance, what is the expected phenotype ratio of a cross between two heterozygous individuals?

Back

1:2:1 (1 homozygous dominant, 2 heterozygous, 1 homozygous recessive)
