2. In some species of Acropora corals in Western Australia, conspecific individuals spawn in two
seasons 6 months apart (half of the population spawns in the spring and half spawns in the
autumn), despite living intermingled on the same reef. This has led the population to become
genetically differentiated between spawning groups (as if they are two separate populations).
Researchers recently sampled 1000 individuals from each spawning population and found that
they had the following genotypes at one particular SNP locus: A. How much have these two
populations of corals differentiated due to being temporally (but not physically) isolated?
Calculate F I S , F ST and F I T for these two populations of corals. (Again, assume equal
population sizes). B. Given that these corals have been on this reef for centuries, they have
almost certainly reached an equilibrium level of differentiation. How much gene flow would
need to be occurring (between spring and autumn) for these populations to be at this degree of
differentiation?.
