What does a phenotype describe?

• The genetic makeup of an organism

• The physical appearance of an organism

• The way an organism interacts with other organisms

• The environment in which an organism lives

What is the difference between dominant and recessive traits?

• Recessive traits are more common than dominant traits in a population.

• Dominant traits are expressed when at least one allele is dominant, while recessive traits are expressed only when both alleles are recessive.

• Dominant traits are always harmful, while recessive traits are always beneficial.

Which word describes the traits you show?

• Genotype

• Phenotype

• Both genotype and phenotype

• Neither genotype nor phenotype

What is a homozygous genotype?

• A genotype with two different alleles for a trait

• A genotype with two dominant alleles for a trait

• A genotype with two recessive alleles for a trait

• A genotype with two identical alleles for a trait

What is a heterozygous genotype?

• A genotype with two identical alleles for a trait

• A genotype with two recessive alleles for a trait

• A genotype with one dominant and one recessive allele for a trait

How can your genes and the environment impact the traits you show?

• The environment has no impact on the traits shown.

• Genes determine traits exclusively, and the environment plays no role.

• The environment can influence the expression of genes and thus affect the traits shown.

• Only the environment determines the traits shown, while genes are not influential.
