Which of the Following Defines the Principle of Linkage

Question

Which of the following defines the principle of linkage?
A) Two or more genes that are physically connected on a chromosome.
B) Genes that are transmitted to the next generation as a group.
C) The process by which genetic information is exchanged between homologous chromosomes.
D) All of the answers are correct.
E) Both two or more genes that are physically connected on a chromosome and genes that are transmitted to the next generation as a group.

Accepted Answer

The principle of linkage refers to the fact that two or more genes that are physically connected on a chromosome are often transmitted together as a group during meiosis. Therefore, choice E, which includes both the idea of physical connection and transmission as a group, is the best choice. The other choices (genes that are transmitted as a group, genetic information exchange between homologous chromosomes) do not fully capture the principle of linkage.
