A male shark has 40 chromosomes in each of its sex cells. How many would be present in its body cells?

• 20
• 40
• 80
• 160

Compared to the number of chromosomes contained in a body cell, how many chromosomes would normally be contained in a gamete?

• The same number
• One-fourth as many
• Twice as many
• Half as many

Chromosomes exchange genetic material during 

• crossing over
• replication
• synthesis
• translation

A human being has a somatic cell that has 46 chromosomes.  What is the haploid number found in a gamete?

• 23
• 46
• 69
• 92

The cells produced via meiosis are called:

• sex cells
• somatic cells
• body cells
• skin cells

Unlike mitosis, meiosis in male mammals results in the formation of

• one haploid gamete
• three diploid gametes
• four diploid gametes
• four haploid gametes

If a somatic cell in a butterfly contains 24 chromosomes, a butterfly egg would contain

The process of crossing over occurs in what phase of meiosis?

• anaphase 1
• prophase 1
• prophase 2
• telophase 1
