Meiosis
Multiple Choice
Meiosis produces which of the following outcomes in sexually reproducing organisms?
A
Two genetically distinct haploid daughter cells produced without recombination
B
Two genetically identical diploid daughter cells used for growth and tissue repair
C
Four genetically identical diploid daughter cells with the same chromosome number as the parent cell
D
Four genetically distinct haploid gametes (cells with half the chromosome number of the parent cell)
Verified step by step guidance1
Understand the purpose of meiosis: it is a type of cell division that reduces the chromosome number by half to produce gametes (sex cells) in sexually reproducing organisms.
Recall that meiosis consists of two consecutive divisions, meiosis I and meiosis II, resulting in four daughter cells.
Recognize that during meiosis, homologous chromosomes undergo recombination (crossing over), which creates genetic variation among the daughter cells.
Note that the daughter cells produced are haploid, meaning they contain half the chromosome number of the original diploid parent cell.
Conclude that meiosis produces four genetically distinct haploid gametes, each with half the chromosome number of the parent cell.
