There are two chromosomes 1- A—B—C—D—E and 2- F—G—H— I, if A—B—C and F—G undergo reciprocal translocation what will not be true?

New sequence at 1 will be C—D—E—F—G

The 1 will then pair with both 1’ and 2’

Pairing will be between same gene loci only

2nd chromosome will become longer

If a part of the chromosome was transferred to a non-homologous chromosome say 1 to 1’. Then which of the following is not true?

The pairing in meiosis will be affected

The chromosome will be torn apart while segregation

In most of the cases, the resultant gamete will be non-viable

The pairing will be between 4 homologous chromosomes
