Which of the following statements about meiosis is true?
A) The chromosome number in the resulting cells is halved.
B) DNA replication occurs before meiosis I and meiosis II.

D) The daughter cells are genetically identical to the parental cell.
E) The chromosome number of the resulting cells is the same as that of the parent cell.

Question

Quizplus · Accepted Answer

Meiosis is a type of cell division that results in four daughter cells, each with half the number of chromosomes as the parent cell. This halving of chromosome number is accomplished through two rounds of cell division (meiosis I and meiosis II), during which the homologous chromosomes separate and then sister chromatids separate. Therefore, statement A is true. Statements B, C, D, and E are all false. DNA replication does occur before meiosis, but it occurs only once, during the interphase stage that precedes meiosis I. The homologs do pair during prophase I, and the resulting daughter cells are genetically unique due to the shuffling of genetic material that occurs during meiosis. Finally, the chromosome number of the resulting cells is halved, not the same as the parent cell.
