Genes located on the same chromosome are inherited together due to linkage. All combinations apart from AABB x aabb exhibit recombination, which does not demonstrate linkage and are therefore unsuitable for linkage studies.

  1. a) Correct
  2. b) Incorrect
  3. c) Indeterminate
  4. d) Not applicable

Correct answer: a) Correct

Solution

The statement is true because linkage refers to the tendency of genes located on the same chromosome to be inherited together, and the AABB x aabb cross is a classic example where no recombination occurs, demonstrating complete linkage.
