Concerning growth in genome size over evolutionary time, which of these is least associated with the others?
A) orthologous genes
B) gene duplications
C) paralogous genes
D) gene families

Question

Quizplus · Accepted Answer

Orthologous genes refer to genes in different species that are derived from a common ancestral gene. The size of the genome may increase as a result of gene duplications, which result in paralogous genes, or by the accumulation of new gene family members. Therefore, A) orthologous genes are the least associated with gene size increase when compared to B) gene duplications, C) paralogous genes, and D) gene families.
