During the 1800s, seal hunters preferred dark-furred seals from natural seal populations. what effect would best describe what this did to the remaining seal populations over time? stabilizing selection creation of a genetic bottleneck special creation no effect at all

If the dark-furred seals from natural seal populations are the seals with most common phenotype (dark fur is phenotype) in the population than the effect is stabilizing selection.

Stabilizing selection is a type of natural selection that favors mean values over the extreme ones. Stabilizing selection is the opposite of disruptive selection which favors both extreme values.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
