1GENBIO2 - GENETICS

Open Ended

Explain the difference between a gene and an allele.

Multiple Choice

Which of the following best describes the difference between a trait and cross pollination?

• A trait is a specific characteristic of an individual, while cross pollination involves two different parents.

• A trait is only found in plants, while cross pollination is found in animals.

• Cross pollination determines the trait of an individual.

• A trait and cross pollination mean the same thing.

Multiple Choice

What is the main focus of the study of genetics?

Multiple Choice

Which of the following statements about alleles is correct?

• Alleles are always identical in every individual.

• Alleles are not located on chromosomes.

• Alleles are the same as chromosomes.
