Test: MCAT Biology

Cellular division is an essential part of the cell cycle. When a cell divides it passes genetic information to daughter cells. The amount of genetic information passed on to daughter cells depends on whether the cell undergoes mitosis or meiosis. Mitosis is the most common form of cell division. All somatic cells undergo mitosis, whereas only germ cells undergo meiosis. Meiosis is very important because it produces gametes (sperm and eggs) that are required for sexual reproduction. Human germ cells have 46 chromosomes (2n = 46) and undergo meiosis to produce four haploid daughter cells (gametes).

1.

Which of the following would occur in humans if meiosis produced diploid gametes?

The number of chromosomes in subsequent generations would be 23

The number of chromosomes in subsequent generations would decrease exponentially

The number of chromosomes in subsequent generations would increase exponentially

The number of chromosomes in subsequent generations would be 92
