Question
A so-called “paradox” regarding this behavior asks why strong preferences for physical traits persist when in theory they will erode any genetic variance. For 10 points each:
[10m] Name this mating behavior, which involves female members of a species going to male gatherings to watch them perform elaborate courtship displays. The greater sage-grouse inflates huge air sacks during this behavior.
ANSWER: lekking [accept lek paradox]
[10h] The lek paradox is typically formulated in terms of this specific component of genetic variance, which, according to Fisher's fundamental theorem, is the only component of genetic variance that contributes to increases in fitness. This component of genetic variance is represented by the diagonal elements of the G-matrix.
ANSWER: additive genetic variance
[10e] Lekking has also been observed in this genus, whose Hawaiian lineage releases pheromones from their abdomen to attract mates. Thomas Hunt Morgan studied sex-linked traits like eye color in a member of this genus.
ANSWER: Drosophila [accept Drosophila melanogaster]
