Quizplus · Accepted Answer

Gene linkage refers to the tendency of genes on the same chromosome to be inherited together because they are physically connected. This can result in the inheritance of different combinations of alleles than expected based on Mendel's Second law. Recombination, or the swapping of genetic material between homologous chromosomes during meiosis, can disrupt this linkage and result in different combinations of alleles for different genes. Sister chromatid exchange, however, does not result in recombination between different chromosomes and therefore does not affect gene linkage. Therefore, both statements A and B apply to the concept of gene linkage, making choice D the correct answer.
