Front

What does this Punnett square and the probabilities of the offspring represent?

Back

A condition in which both alleles for a gene are expressed so that both traits are visible is known as ---

Back

Codominance

Front

What is the dominant trait?

Back

yellow pea seeds

Front

A calico cat shows both the traits for orange fur and black fur. What kind of allele expression is this?

Back

Codominance

Front

What is a Punnett square used for?

Back

To predict the genetic makeup of offspring from parental genotypes.

Front

Define genotype.

Back

The genetic constitution of an individual, represented by alleles.

Front

Define phenotype.

Back

The observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even if only one copy is present; recessive alleles require two copies to express their trait.

Front

What does homozygous mean?

Back

Having two identical alleles for a particular gene.
