A scientist conducted a study of an organism and found that its body cells contained 40 chromosomes. These cells were cultured in the laboratory, and cell division was observed. What difference, if any, would a scientist expect to observe between body cell division and sex cell division in the organism?

• Body cells divide by mitosis, and sex cells divide by meiosis.

• Body cells divide by meiosis, and sex cells divide by mitosis.

• There is no difference; body cells and sex cells both divide by mitosis.

• There is no difference; body cells and sex cells both divide by meiosis.
