Which of the following statements regarding gene linkage is correct?

B) The observed frequency of recombination of two genes that are far apart from each other has a maximum value of 100%.
C) All of the traits that Mendel studied-seed color, pod shape, flower color, and others-are due to genes linked on the same chromosome.
D) Linked genes are found on different chromosomes.

Question

Quizplus · Accepted Answer

Gene linkage refers to the tendency for genes located close together on a chromosome to be inherited together. The closer two genes are on a chromosome, the less likely it is that a crossover event will occur between them during meiosis, and the higher the probability that they will be inherited together as a unit. This is known as linkage, and the degree of linkage between two genes is proportional to the distance between them on the chromosome.
