In meiosis, what is a tetrad?
A
A set of four haploid cells produced at the end of meiosis II
B
A structure formed when two homologous chromosomes (each consisting of two sister chromatids) pair during prophase I, totaling four chromatids
C
A group of four chromosomes produced after separation of sister chromatids in anaphase II
D
A pair of sister chromatids joined at a centromere after DNA replication
Verified step by step guidance1
Understand that meiosis is a process of cell division that reduces the chromosome number by half, producing haploid cells from a diploid cell.
Recall that during prophase I of meiosis, homologous chromosomes (one from each parent) pair up closely in a process called synapsis.
Recognize that each homologous chromosome consists of two sister chromatids, so when two homologous chromosomes pair, they form a group of four chromatids.
This group of four chromatids is called a tetrad, which is a key structure allowing crossing over and genetic recombination to occur.
Note that the tetrad is not the final product of meiosis but a temporary structure formed during prophase I, distinct from the haploid cells produced at the end of meiosis II.
