Which of the following best describes meiosis?

• Cell division producing identical cells

• Cell division producing gametes with half the number of chromosomes

• Cell division in bacteria

• Cell division for growth and repair

What is the primary purpose of meiosis?

• To create identical daughter cells

• To increase chromosome number

• To produce haploid gametes for sexual reproduction

• To make somatic cells

How many cell divisions occur during meiosis?

• One

• Two

• Three

• Four

What is the result of meiosis in terms of chromosome number?

• Diploid to diploid

• Haploid to diploid

• Diploid to haploid

• Haploid to haploid

What process during meiosis increases genetic variation?

• DNA replication

• Crossing over

• Cytokinesis

• Mutation

Crossing over occurs during which phase?

• Prophase I

• Metaphase I

• Anaphase II

• Telophase I

What is the outcome of crossing over?

• New combinations of alleles

• Identical chromosomes

• DNA damage

• Chromosome duplication

Independent assortment refers to:

• Random distribution of chromosomes during meiosis

• Copying DNA before meiosis

• Random mutation

• Random fertilization

The cells produced by meiosis are:
