Answer:
Anaphase 1: 32 chromosomes
Anaphase 2: 16 chromosomes
Explanation:
Tetrads are formed during meiosis I, where homologous chromosomes pair up and exchange genetic material in a process called crossing over. Each tetrad contains 4 chromatids, which means that a diploid cell with 16 tetrads will have 64 chromatids in total.
During anaphase 1 of meiosis, the homologous chromosomes separate and move to opposite poles of the cell. Each pole will have 16 chromosomes, since each homologous pair has already been separated. Therefore, the total number of chromosomes at anaphase 1 will be 32.
During anaphase 2 of meiosis, the sister chromatids of each chromosome separate and move to opposite poles of the cell. Since each chromosome only has one chromatid at this point, the total number of chromosomes at anaphase 2 will be 16.
Therefore, the answer is option C: 16 chromosomes at anaphase 2 and 32 chromosomes at anaphase 1.

If a cell consists of 16 tetrads then number of chromosomes that are present in diploid cell is equal to 32.
During the first division there is reduction in the number of chromosome to half.
As a result of this chromosomes will be 16 in phase 1. However the second meiotic division is an equational division and there is no decrease in the number of chromosomes.
Hence the number of chromosome in meiosis 2 will be equal to 32.
So, correct answer is option (C)...
