Question
The first scientist behind this statement regarded it as “very simple” and “of the multiplication-table type.” For 10 points each:
[10e] What statement holds that allele frequencies will stay constant in a large, stable population?
ANSWER: Hardy–Weinberg principle [or Hardy–Weinberg equilibrium]
[10m] There is debate over whether this specific process can happen without segregation by niche or behavior. This process is hard to distinguish from alternatives in which gene flow occurs through secondary contact, even in the cichlids (“sick-lids”).
ANSWER: sympatric speciation [prompt on speciation]
[10h] Hybridization causes instant sympatric speciation but is rare in mammals, which this scientist attributed to sex chromosome ratios in triploids and tetraploids. This scientist coined the term “dosage compensation” and elaborated on Dobzhansky’s theory of isolation during speciation.
ANSWER: Hermann Muller [or Hermann Joseph Muller; accept Dobzhansky–Muller model; reject “Paul Hermann Muller”]
