Which of the following is not one of the principles of linkage that Morgan obtained from his experiments?
A) Genes that are on the same chromosome may be inherited together.
B) Crossing over exchanges pieces of chromosomes and creates new allele combinations.
C) The likelihood of crossing over occurring between two genes is dependent on the distance of the genes from one another.
D) Genes that are on the same chromosome are always transmitted together as a unit.

Question

Option D is not one of the principles of linkage established by Morgan. In fact, the principle of independent assortment states that genes on the same chromosome can be transmitted independently if they undergo recombination via crossing over. Therefore, genes on the same chromosome are not always transmitted together as a unit.
