Front

What is the genotype of two heterozygous parents for a dominant trait?

Back

Front

What does the fossil record indicate about the evolution of horses?

Back

The horse evolved from a much smaller organism.

Front

What is a common ancestor?

Back

Front

What is the significance of genetic variation in a population?

Back

Genetic variation allows for adaptation and evolution in response to environmental changes.

Front

What is the difference between dominant and recessive traits?

Back

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

Front

What is the role of mutations in evolution?

Back

Mutations introduce new genetic variations, which can lead to evolutionary changes.

Front

How do environmental factors influence genetic traits?

Back

Environmental factors can affect the expression of genetic traits, but the genes themselves come from parents.
