Answer 1

I believe the answer is D; Translocation

Answer 2

The correct answer would be D) translocation.

Chromosomal translocation refers to the rearrangement or exchange of part of non-homologous chromosomes.

It can be of two types:

Balanced: It is an even exchange in which genetic information is neither lost or gained and genes are usually fully functional.

Unbalanced: It is an unequal exchange of materials during which some part of a chromosome may get lost or gained due to which function of a gene may get lost.

It can cause various diseases such as cancer especially leukemia and lymphoma, infertility, XX male syndrome et cetera.
