What does the term "haploid" mean?

• The daughter cells have no chromosomes, and are non-functioning

• The daughter cells have half the amount of chromosomes than the parent cells

• The daughter cells contain double the amount of chromosomes

• None of the listed answers are correct

Who is considered the father of genetics?

• I don't know

• Charles Darwin

• Gregor Mendel

• Mr. Smith

What happens when two chromosomes cross-over in meiosis?

• The genetic material of the chromosomes mixes, creating diversity

• The chromosomes combine into one large chromosome

• They can't cross over

• More chromosomes end up being created

How many divisions occur during meiosis?

• 100

• 2

• 4

• 1

What does the term "heterozygous" mean?

• Having the same allele of a gene

• Having no alleles of a gene

• Having two different alleles of a gene

• I don't know
