Punnet Squares, Blood Types, and Heredity Review

Front

What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the genotype and phenotype combinations of a genetic cross.

Front

What does genotype refer to?

Back

Genotype refers to the genetic makeup of an organism, specifically the alleles it possesses.

Front

What is phenotype?

Back

Phenotype is the physical appearance or observable traits of an organism.

Front

What is the difference between homozygous and heterozygous?

Back

Homozygous means having two identical alleles for a trait, while heterozygous means having two different alleles for a trait.

Front

What is codominance?

Back

Codominance is a form of inheritance where both alleles in a heterozygote are fully expressed, resulting in a phenotype that is neither dominant nor recessive.

Front

What is incomplete dominance?

Back

Incomplete dominance is a type of inheritance where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

Front

What are the blood types in humans?

Back

The main blood types in humans are A, B, AB, and O.

Front

Which blood type is considered the universal donor?

Back

Blood type O is considered the universal donor because it can be given to any other blood type.

Front

Which blood type is considered the universal recipient?

Back

Blood type AB is considered the universal recipient because it can receive blood from any other type.

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.
