Which of the Following Pairs is Incorrectly Matched

Question

Which of the following pairs is incorrectly matched?
A)orthologous genes - speciation with divergence of genes
B)paralogous genes - gene duplication and divergence
C)orthologous and paralogous genes - both lead to speciation
D)paralogous genes - divergence within a species

Accepted Answer

Orthologous and paralogous genes may both contribute to the evolution of genetic variation within and between species, but only orthologous genes are directly involved in speciation events through divergence and differentiation over time. Paralogous genes may diverge within a species or lineage, but this does not necessarily lead to speciation unless there are additional factors at play. Therefore, choice C is incorrectly matched as it implies that both types of genes lead to speciation.
