A/An ___ cell contains half of the number of chromosomes that its parent cell has. Cancer cells are less likely than normal cells to undergo _, or programmed cell death. The _ is the region within a dividing cell where chromatids and homologous chromosomes align in both mitosis and meiosis. _ occurs when an unfertilized egg cell gives rise to an embryo. This form of asexual reproduction is more common in reptiles and fish. _ results in four haploid daughter cells that are genetically distinct. The point where chromosomes cross over and exchange DNA during meiosis is called the ___.

Answers may vary. Meiosis results in four daughter cells, whereas mitosis produces only two daughter cells. Meiosis has two distinct phases, meiosis I and meiosis II, whereas mitosis takes place in a single cycle. Daughter cells in meiosis are genetically unique from one another. Mitotic daughter cells are genetically identical. Both mitosis and meiosis have similar basic steps (prophase, metaphase, anaphase, and telophase). Both mitosis and meiosis have cell cycle regulation mechanisms, including checkpoints and cell cycle regulators, which allow them to consistently produce normal cells.

Please find the answers to the blank spaces pertaining to reproduction in the questions below:

REPRODUCTION FACTS:

A sex cell contains half of the number of chromosomes that its parent cell has. This is because the sex cell is formed as a result of meiosis.

Cancer cells are less likely than normal cells to undergo apoptosis or programmed cell death. Apoptosis is a phenomenon whereby cells die in a programmed manner.

The metaphase plate is the region within a dividing cell where chromatids and homologous chromosomes align in both mitosis and meiosis.

Parthenogenesis occurs when an unfertilized egg cell i.e. an egg that has not been fertilized by a sperm cell, gives rise to an embryo. Parthenogenesis is a form of asexual reproduction more common in reptiles and fish.

Meiosis is a kind of division which results in four haploid daughter cells that are genetically distinct from one another.

The point where chromosomes cross over and exchange DNA during meiosis is called the chiasma (plural- chiasmata).
