Question

what will be the number of chromatids in prophase 1 of a cell having 10 bivalents/

Answer 1

Answer:

A bivalent is one pair of chromosomes (sister chromatids) in a tetrad. A tetrad is the association of two pairs of homologous chromosomes (4 sister chromatids) physically held together by at least one DNA......

Answer 2

Answer:

40

Prophase 1 of meiosis has 5 phase in total.

1. Leptotene

2. Zygotene

3. pachytene

4. Diplotene

5. Diakinesis

In zygotene phase, chromosome exit as bivalent hence bivalent can be defined as the pair of two sister chromosome ( 1 bivalent = 4 chromatid)

and they are bind together by synaptic complex protein.

In the later stage pachytene, these bivalents are arrange into tetrad and in this phase the process of recomination occurs.
