Multiple Choice
In a typical diploid organism, what is the end result of meiosis in terms of the number and chromosome content of daughter cells?
A
Four genetically distinct haploid cells, each with half the chromosome number of the original diploid cell
B
Two genetically identical diploid cells, each with the same chromosome number as the original cell
C
Two genetically distinct haploid cells, each with half the chromosome number of the original diploid cell
D
Four genetically identical diploid cells, each with the same chromosome number as the original cell
Verified step by step guidance1
Recall that meiosis is a type of cell division that reduces the chromosome number by half, producing cells that are haploid (n) from an original diploid (2n) cell.
Understand that meiosis consists of two consecutive divisions: meiosis I and meiosis II. Meiosis I separates homologous chromosomes, and meiosis II separates sister chromatids.
Recognize that the process results in four daughter cells because one diploid cell undergoes one round of DNA replication followed by two rounds of cell division.
Note that the daughter cells are genetically distinct due to crossing over (recombination) during prophase I and the independent assortment of chromosomes during metaphase I.
Conclude that the final product of meiosis is four genetically distinct haploid cells, each containing half the chromosome number of the original diploid cell.
