Explanation / Answer

21.Answer is (d)-->Disjunction is the phenomenon where after the meiosis gametes have either too many or too few chromosomes. But if everything goes smooth in the process of meiosis the diploid(2n) cell divide into four haploid(n) cells.

And the process of disjunction occurs only in anaphase I of meiosis I and anaphase II of meiosis II where the two chromosomes in each homologous separate and migrate toward opposite poles.

22. answer is d.

The mouse died because of transforming principle. the poison released from heat killed bacteria has made the friendly bacteria virulent.

Thanks!!
