Question
Pencil and paper ready. An allele has 80% frequency in a population. For 10 points each:
[10h] If there are only two alleles for the trait and they’re in Hardy–Weinberg equilibrium, what percentage of the population is heterozygous? You have 10 seconds.
ANSWER: 32% [or 0.32; or 8/25]
[10e] Not a biologist himself, G. H. Hardy was introduced to genetics over a game of cricket with this scientist. He names a “square” used to predict offspring genotypes.
ANSWER: Reginald Crundall Punnett
[10m] While Hardy was intuiting the equilibrium on a cricket pitch, actual biologist Wilhelm Weinberg derived the same formulas from careful studies of these people. Studies of these people were historically—and often wrongly—used to decouple genetic and environmental contributions to traits.
ANSWER: twins [or twin studies; or identical or monozygotic twins; or fraternal or dizygotic twins; prompt on siblings or brothers or sisters or family members or similar answers]
