What blood types can children inherit from a woman with Type AB blood and a man with Type A blood (I^Ai)?

Back

Back

0% chance.

Front

What does it mean for a trait to be X-linked recessive?

Back

Front

Back

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

Front

What is Mendelian inheritance?

Back

The inheritance patterns described by Gregor Mendel, including dominant and recessive traits.

Front

What is the significance of a pedigree in genetics?

Back

It traces the inheritance of traits through generations.

Front

What is the difference between genotype and phenotype?

Back

Front

What is an allele?

Back
