Mouse Genetics GIZMO Review

Front

What is a recessive allele?

Back

A form of a gene that is only expressed if the organism receives one from each parent. Shows as a trait.

Front

What is a genotype?

Back

The genetic makeup of an organism.

Front

What is a phenotype?

Back

The physical appearance of an organism.

Front

What is a purebred organism?

Back

The offspring has parents with the same traits. Example: two parents with blue eyes.

Front

What is a dominant allele?

Back

A form of a gene that is always expressed if the organism has it. Shows as a trait.

Front

What does it mean for a trait to be inherited?

Back

It means that the trait is passed from parents to offspring through genes.

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.

Front

What is the significance of the Punnett square?

Back

It is a tool used to predict the genetic outcomes of a cross between two organisms.

Front

What is the expected phenotype ratio in a monohybrid cross?

Back

The expected phenotype ratio is typically 3:1 for dominant to recessive traits.

Front

What is the role of alleles in genetics?

Back

Alleles are different forms of a gene that determine specific traits.
