During prophase I, all four chromatids of the two homologues become closely associated as a result of pairing, forming a structure known as a tetrad or bivalent.
<h3>What is a tetrad?</h3>
A tetrad is a structure formed during the prophase I stage of meiosis I whereby two homologous chromosomes pair together.
Meiosis occurs in two stages of division namely;
- meiosis I
- meiosis II
In meiosis I, homologous chromosomes are separated but are first paired during the prophase stage to form the tetrad or bivalent structure.
Therefore, during prophase I, all four chromatids of the two homologues become closely associated as a result of pairing, forming a structure known as a tetrad or bivalent.
