Genetics HW Flashcard: Complex Inheritance

Front

What does incomplete dominance mean?

Back

Traits are blended together in the phenotype.

Front

Can a man with type AB blood be the father of a type O baby if the mother is type A?

Back

No, because type O requires two recessive alleles.

Front

What terms best describe the inheritance of human blood types?

Back

Codominance and multiple alleles.

Front

What is an example of multiple alleles in genetics?

Back

The different alleles for fur color in cats.

Front

What pattern of inheritance is shown when a red flower and a white flower produce pink flowers?

Back

Incomplete dominance.

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed.

Front

What is an example of codominance in humans?

Back

AB blood type, where both A and B alleles are expressed.

Front

What is the definition of multiple alleles?

Back

More than two alleles exist for a genetic trait.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles mask the effect of recessive alleles in heterozygotes.

Front

What is a phenotype?

Back

The observable characteristics or traits of an organism.
