Blue.

Front

What does the term 'heterozygous' mean in genetics?

Back

An organism that has two different alleles for a trait (e.g., Tt).

Front

What is the meaning of incomplete dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a blended phenotype.

Front

What is an allele?

Back

One form of a gene.

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 physical traits.

Front

What is a homozygous genotype?

Back

A genotype consisting of two identical alleles for a trait (e.g., TT or tt).

Front

What is the role of alleles in inheritance?

Back

Alleles are different versions of a gene that determine specific traits in an organism.

Front

What is the principle of segregation in genetics?

Back

The principle that during the formation of gametes, the two alleles for a trait separate from each other.

Front

What is a dominant allele?

Back

An allele that expresses its trait even in the presence of a recessive allele.
