Inversions May Be Hard to Detect Because They

Question

Inversions may be hard to detect because they
A) never visibly change chromosome banding patterns.
B) increase recombination in heterozygotes.
C) do not usually cause an abnormal phenotype.
D) normally are removed immediately in natural populations.
E) cannot involve more than 1000bp.

Accepted Answer

Inversions do not usually cause an abnormal phenotype, which can make them hard to detect. Additionally, they may not visibly change chromosome banding patterns and are not always removed immediately from natural populations. While inversions can affect recombination in heterozygotes, this is not a primary reason why they may be hard to detect. The size of an inversion can vary and is not limited to 1000bp, so this is also not a true statement.
