Which of the following statements regarding gene linkage is correct?
A) The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them.
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 colour, pod shape, flower colour, 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 of genes on the same chromosome to be inherited together. The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them, meaning that they are more likely to be inherited together. Option B is not true because the observed frequency of recombination has a maximum value of 50%, not 100%. Option C is incorrect because not all traits that Mendel studied are due to genes linked on the same chromosome, and option D is incorrect because linked genes are found on the same chromosome.
