Question 4 9 pts Select all of the following statements that are true concerning the daughter cells of meiosis: Hint: • Overview of Meiosis e video Compare Mitosis and Meiosis e video • Textbook chapter 11 section 11.1 The daughter cells are genetically identical to each other, but genetically different from the original parent cell. The daughter cells contain replicated chromosomes. Each daughter cell has half as many chromosomes as the original parent cell Each daughter cell only contains one member/chromosome of each homologous pair. The daughter cells are somatic haploid cells

Answer 1

Meiosis is a process of cell division in which a single cell divides two times and at the end of the cycle, four haploid cells are produced which have half the number of chromosomes of the parent cell. meiosis occurs in the gametic cells of the body.

the statements which are true regarding meiosis are -

• the daughter cells are genetically identical to each other, but genetically different from the original parent cell - the four daughter cells produced at the end of the cycle of meiosis are all haploid i.e. contains the "n" number of chromosomes which are genetically different from the original parent cell which is diploid (2n) in nature.
• the daughter cells contain replicated chromosomes - in meiosis, chromosomes are replicated only one time in the "S" phase but no DNA replication occurs between meiosis I and meiosis II. (so this can be understood in the context of meiosis I and II, that daughter cells after meiosis I contains replicated chromosomes but daughter cells after meiosis II do not contain replicated chromosome).
• each daughter cell has half as many chromosomes as the original parent cell - the four daughter cells produced at the end of the cycle of meiosis are all haploid i.e. contains the "n" number of chromosomes which are genetically different from the original parent cell which is diploid (2n) in nature.

the wrong statements are -

the daughter cells are somatic haploid cells - the daughter cells are haploid but they are not somatic cells because as discussed above, meiosis occurs in gamete cells to reduce their chromosome number so that after fertilization, ploidy level remains balanced.

each daughter cell only contains one member or chromosome of each homologous pair - each daughter cell only contains one member or chromosome but they are not of homologous pair, they are of sister chromatids.
