Question

if 30 terad appear in zygotene than number of chromosome in endosperm is?​

Answer 1

Answer:

When the zygotene stage begins, the homologous chromosomes pair up to for bivalents or tetrads.

If there are 60 chromosomes in G1 phase, then after S phase, there would be 120 chromosomes.

And we know that each bivalent is formed of 4 chromosomes so there will be 120%4=30bivalents in zygotene stage.

Hence, 30 number of bivalents in zygotene stage, if there are 60 chromosomes in G1 phase.

So, the correct answer is '30'.
