Question

The formation of the bivalent during meiosis is?

1) The pairing of homologous chromosomes
2) The separation of sister chromatids
3) The formation of spindle fibers
4) The replication of DNA

Answer 1

The formation of the bivalent during meiosis is the pairing of homologous chromosomes.

Step-by-step explanation:

The formation of the bivalent during meiosis is 1) The pairing of homologous chromosomes.

During prophase I, homologous chromosomes pair up to form a bivalent or a tetrad. This pairing allows for crossing-over, where genetic material is exchanged between the homologous chromosomes. Each bivalent consists of four chromatids, two from each homologous chromosome.
