How many possible combinations of the three sets of dyads will result after the completion of anaphase i?

8 possible combinations of the three sets of dyads will result after the completion of anaphase i.

Explanation:

Dyads are coupled chromosomes coupled by one paternal and another maternal chromosome. They are the pair of homologous chromosomes or sister chromatids and consists of two parts. It is found during Anaphase-I. During anaphase the dyads normally split and migrate independently to either sides and hence causing 8 possible combinations at the end.

It separates homologous chromosomes into two and send it to the poles. During the process combination of the maternal and paternal chromosomes happen and then split at the end of the anphase-I.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
