Which of the following is a true statement regarding inversions and recombination in chromosomes?
A) Inversion typically suppresses recombination
B) The inhibition of crossing over that occurs near the breakpoints of the inversion is compounded by the selective loss of chromosomes that have undergone crossing over within the inverted region.
C) Crossing over is usually inhibited near the breakpoints of a rearrangement in heterozygous condition
D) All of these are true
E) None of these are true

Question

Quizplus · Accepted Answer

A) Inversions near or crossing over in the inversion.
B) Selective loss occurs because the resulting recombinant chromosomes have large duplications and deletions.
C) Heterozygous condition means having two different versions of a gene (alleles), which can interfere with crossing over within the inverted region.
Therefore, all of the given statements are true.
