What is a genotype?

Back

A genotype is the genetic makeup of an organism, representing the alleles inherited from its parents.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What is a dominant allele?

Back

A dominant allele is an allele that expresses its trait even when only one copy is present in the genotype.

Front

What is a recessive allele?

Back

A recessive allele is an allele that only expresses its trait when two copies are present in the genotype.

Front

What is a Punnett square?

Back

A Punnett square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles.

Front

What is the purpose of a test cross?

Back

A test cross is used to determine the genotype of an individual with a dominant phenotype by crossing it with a homozygous recessive individual.

Front

What is a carrier in genetics?

Back

A carrier is an individual who has one copy of a recessive allele for a trait but does not exhibit the trait.

Front

What blood types can a person with type AB blood have as parents?

Back

A person with type AB blood can have parents with blood types A, B, AB, or O, but not OO.

Front

What is the expected percentage of female offspring that will be carriers for a recessive disease if one parent is a carrier and the other is affected?

Back

50% of the female offspring will be carriers for the recessive disease.
