Question

A diploid cell which consist 46 chromosomes, than how many bivalant or tetrad found in Zygotene

• A. 46
• B. 23
• C. 92
• D. None

Answer 1

The correct option is B 23

A bivalent, sometimes referred to as a tetrad, is the association of a pair of homologous chromosomes physically held together by at least one DNA crossover. So 46 chromosomes will make 23 pairs and further form 23 bivalent or tetrads.

So the correct answer should be option "23".
