During prophase 1 of meiosis, crossing over occurs. What is happening in the cell during crossing over?

• Tetrads are pulled apart so that the number of chromosomes is cut in half.

• Chromosomes cross over the cell membrane using active transport.

• DNA is replicated so that the number of chromosomes stays the same in each daughter cell.

• Homologous chromosomes trade genetic information so that each gamete is unique.

During normal mitotic cell division, a parent cell having four chromosomes will produce two daughter cells, each containing

• 4 chromosomes

• 2 chromosomes

• 8 chromosomes

• 16 chromosomes

• somatic cell

• gamete

• stem cell

Which of the following statements about meiosis is true?

• Every tissue in the body has some cells that occasionally undergo meiosis.

• Meiosis takes place in reproductive tissue and produces gametes.

• Meiosis always takes place after a cell undergoes mitosis.
