Please Explain

Do not answer if you are not sure..I'll report if there is an unexplained answer/ or completely wrong answer.

Genes A and B are separated by 26 m.u. on the X chromosome of Drosophila. You collect individual Drosophila from nature and isolate five different X chromosomes. You make heterozygous females in every pairwise combination of these chromosomes, and for each combination you measure the recombination frequency between A and B. The results are shown in the table below. If chromosome 1B is defined as the "normal" structure, which of the chromosomes contain an inversion relative to 1B?

Explanation / Answer

An inversion relative chromosome is the one which is having a segment of a chromosomes that are reversed end to end. An inversion occurs when chromosome rearrangement or breakage within itself.

Thus, the correct options are 1A and 1D.
