Multiple Choice
In a typical diploid organism, what is formed at the end of meiosis (after meiosis II)?
A
A single polyploid cell containing twice the original amount of DNA
B
Four genetically distinct haploid daughter cells (gametes or spores), each with one set of chromosomes
C
Four genetically identical diploid daughter cells produced by two rounds of DNA replication
D
Two genetically identical diploid daughter cells, each with the same chromosome number as the parent cell
Verified step by step guidance1
Recall that meiosis consists of two consecutive divisions: meiosis I and meiosis II, following a single round of DNA replication.
Understand that meiosis I is a reductional division where homologous chromosomes are separated, reducing the chromosome number by half, resulting in two haploid cells.
Recognize that meiosis II is an equational division similar to mitosis, where sister chromatids are separated, producing four cells in total.
Note that the cells produced at the end of meiosis are haploid, meaning they contain one set of chromosomes, and are genetically distinct due to crossing over and independent assortment.
Conclude that the final products of meiosis are four genetically distinct haploid daughter cells, which can develop into gametes or spores.
