This process allows for the accumulation of “forbidden” mutations according to a 1970 book by Susumu Ohno titled Evolution by this process. For 10 points each:
[10h] Name this process, which often generates pseudogenes in the absence of selection pressure. Degeneration and complementation follow this process in one model of subfunctionalization proposed by Allan Force and coworkers.
ANSWER: gene duplication [accept locus duplication or sequence duplication; accept duplication–degeneration–complementation or DDC model; accept answers that include generating copy number variations or CNVs; prompt on gene or locus or sequence repeats; prompt on polyploidy]
[10e] Amplification of duplicate genes that increase this quantity may explain why rare but beneficial mutations become more common over time. At the organismal level, this quantity denoted w measures reproductive success.
ANSWER: fitness [accept absolute or relative fitness]
[10m] Another model of subfunctionalization describes a single gene “escaping” conflicts named for this adjective before duplication occurs. Darwin’s finches evolved due to rapid diversification also known by this adjective.
ANSWER: adaptive [accept escape from adaptive conflict or EAC; accept adaptive radiation; prompt on evolutionary radiation]
