Which of the following statements about chromosomal inversions is not true?
a. an inversion can break a gene into two parts and separate each to different locations.
b. the expression of the gene may be altered due to the positional effect.
c. the individual organisms have neither lost nor gained any genetic material.
d. individuals heterozygous for inversions may end up producing abnormal gametes.
e. the inversion mutations will not likely have pronounced phenotypic effects since there is no loss of genetic material.

Answer is E.

Explanation:

Chromosomal inversion is a situation involving the segment of a chromosome where it is turned upside down and reinserted back into the chromosome. This usually occurs because of a breakage and rearrangement occurring within a single chromosome.

It is of a two types, these are

* Paracentric chromosomal inversion - a type where a segment not including the centromere is snipped out, inverted, and inserted back to its location on chromosome.

* Pericentric chromosomal inversion - is a type where a segment including the centromere is snipped out, inverted, and inserted back to its original location on chromosome.
