• The entire DNA of an organism.

• A segment of DNA that determines a specific physical appearance.

• A portion of DNA that contains instructions for a trait.

Which of the following is a type of genotype?

• Phenotypic Dominant

• Homozygous Recessive

• Allelic Expression

• Chromosomal Trait

How is a recessive allele expressed as a trait?

• It is always expressed, regardless of other alleles.

• It is expressed only when paired with a dominant allele.

• It is expressed only when both alleles are recessive.

• It is never expressed in an organism's physical appearance.
