Incomplete Dominance and Codominance

Front

What is the definition of dominant trait?

Back

A dominant trait is a trait that will always be expressed if present because it masks the expression of other traits.

What color flowers result from crossing a red flower (RR) with a white flower (WW) in snapdragons?

Back

The flowers that are RW will be pink.

Front

What is the term for the allele combinations in an organism?

Back

Genotype.

Front

What is codominance?

Back

Codominance is a condition in which both alleles for a gene are expressed so that both traits are visible, such as blue and yellow spots.

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits or characteristics.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene.

Front

What is an example of codominance in animals?

Back

An example of codominance is in certain breeds of cattle, where both red and white hairs are expressed, resulting in a roan coat.

Front

What is an example of incomplete dominance in plants?

Back

An example of incomplete dominance is the flower color in snapdragons, where crossing red and white flowers produces pink flowers.
