Question

A normal chromosome and its homolog carrying an inversion are given. The dot (•) represents the centromere. Normal: M N • O P Q R S T Inversion: M Q P O • N R S T What type of inversion is present and what is the name of the structure that will form during synapsis?

Answer 1

Answer:

Pericentric, inversion loop.

Explanation:

Chromosomal inversion may be defined as the rearrangement of chromosome that may get reversed and attached. Two main types of inversion are pericentric inversion and paracentric inversion.

The pericentric inversion involves the inversion of chromsome and centromere is involved in this inversion. M Q P O • N R S T , in this case centromere is present and shows the pericentric inversion. The structure that forms during the synapsis is known as inversion loop.

Thus, the answer is pericentric, inversion loop.
