Question

the number of bivalent are 20. what will be the number of chromosomes during anaphase 2 at each pole?​

Answer 1

Answer:

20

Explanation: each bivalent have 2 no of chromosome so there are 20 bivalent means 40 no of chromosomes

After anaphase 2 each pole 20 chromosomes because meiosis division produces haploid gamates

Answer 2

20 chromosomes

Explanation:

• Meiosis is a reductional division in which the number of the chromosome becomes half in the daughter cells. One bivalent contains two chromosomes so 20 bivalent will contain 40 chromosomes.
• In meiosis one, the chromosome will become half and all cells will have 20-20 chromosomes.  
• In meiosis 2 or anaphase 2 the chromosome number will remain the same and 20 chromosomes will be present during anaphase 2 at each pole. Therefore the correct answer is 20.
