Question

Inversions can lead to a deletion or duplication in the chromosome.

(a) True

(b) False

This question was addressed to me in an international level competition.

I would like to ask this question from Gene Expression Control in portion Control of Gene Expression of Cell Biology

Answer 1

Right answer is (a) True

For explanation I would say: Inversions are chromosomal aberrations that occur when there are two breaks in the chromosome and the segment amidst the breaks becomes resealed in a reverse orientation. During crossing over the aberrant chromosome does not pair properly with its homologue, the gametes then generated by meiosis either possess duplication or a deletion.
