Different genes on the homologous chromosomes e. The recessive phenotype

Explanation / Answer

9) Answer is option a.

Unregulated meiosis is not the cause of tumor because meiosis occurs in germ cells.

So,option a is not correct.

10)Answer is option e.

Chromatids pulled apart in anaphase of mitosis.

So option a,b,c and are not correct.

Hence,option e is correct.

11)Answer is option b.

Crossing over occurs in the prophase I of meiosis.

So option a,c,d and e are not correct.

Hence,option b is correct.

12)Answer is option b.

Meiosis leads to variation which is the main cause of genetic diversity.

So,option a,c,d and e are not correct.

Hence,option b is the correct option.
