Meiosis
Multiple Choice
Which statement best describes meiosis?
A
A specialized cell division that produces genetically diverse haploid gametes by including one round of DNA replication followed by two rounds of division.
B
A type of cell division in which chromosome number is doubled to produce tetraploid daughter cells.
C
A cell division that produces two genetically identical diploid daughter cells after one round of DNA replication and one division.
D
A process in which homologous chromosomes separate during a single division to form two genetically identical haploid cells.
Verified step by step guidance1
Understand that meiosis is a specialized type of cell division that reduces the chromosome number by half, producing haploid cells from a diploid parent cell.
Recognize that meiosis involves one round of DNA replication, where chromosomes are duplicated, followed by two successive rounds of cell division, called meiosis I and meiosis II.
Note that meiosis I separates homologous chromosomes, which contributes to genetic diversity through processes like crossing over and independent assortment.
Observe that meiosis II separates sister chromatids, similar to mitosis, resulting in four genetically diverse haploid gametes.
Compare meiosis to mitosis and other cell division types to identify that meiosis uniquely produces genetically diverse haploid cells through two divisions after one DNA replication.
