Which of the following statements correctly describes gene linkage?
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)Linked genes always assort independently.
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 during meiosis. The closer two genes are on a chromosome, the less likely they are to be separated by a crossover event during meiosis, meaning they will be inherited together. Conversely, genes that are far apart from each other on a chromosome are more likely to undergo a crossover event, leading to the shuffling of genetic information and increased recombination frequency. Therefore, choice A accurately describes gene linkage.
