Therefore … WebMay 30, 2024 · During prophase 1 of meiosis I, the homologous pair of chromosomes come very close together and bind tightly to each other so that they almost act as one single unit. This unit is called a bivalent or a tetrad (indicating that each chromosome consists of two sister chromatids so the sum of bivalent is four chromatids).

The formation of a bivalent occurs during the first division of meiosis (in the zygotene stage of meiotic prophase 1). In most organisms, each replicated chromosome (composed of two identical sister chromatids ) elicits formation of DNA double-strand breaks during the leptotene phase. These breaks are repaired by homologous recombination, that uses the homologous chromosome as a template for repair. The search for the homologous target, helped by numerous proteins co… WebApr 3, 2024 · Hint: During the prophase of meiosis I homologous chromosomes pair and form neurotransmitters. The combined chromosomes are called bivalents. The bivalent has two chromosomes and four chromatids, with one chromosome coming from each parent. Complete answer: -Meiosis is described by the pairing of homologous chromosomes.
