question 23

Multiple Choice

Disruptive selection is a key component of sympatric speciation because it acts against the homogenizing effect of gene flow between the diverging populations. Imagine a case in which a bird population is undergoing disruptive selection on bill size in response to the availability of seeds to eat. The birds' environment contains two seed types, large and small, and lacks medium-sized seeds. Assume that a bird's ability to eat a seed is a direct function of its bill size (large bills are good for large seeds, and so on) . Disruptive selection acts against birds with:

• A)large bills.
• B)small bills.
• C)large bills and birds with small bills.
• D)intermediate (medium-sized)bills.
• E)medium bills and birds with large bills.
