Back

Bb

Front

What color are flowers that are Rr when a red flower (RR) is crossed with a white flower (rr)?

Back

Pink

Front

What is the physical expression of a trait called?

Back

Phenotype

Front

What does incomplete dominance involve?

Back

Heterozygous offspring resulting in an intermediate between the two dominant traits.

Front

What is the definition of genotype?

Back

The genetic makeup of an organism.

Front

What is codominance?

Back

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

Front

In a genetic cross, what does the term 'dominant' refer to?

Back

An allele that masks the effect of a recessive allele.

Front

What is the difference between phenotype and genotype?

Back

Phenotype is the physical expression of a trait, while genotype is the genetic makeup.

Front

What is the expected phenotypic ratio in a monohybrid cross?

Back

3:1 ratio of dominant to recessive traits.
