If one genotype in a genetically variable population is favored in dry years and a different genotype is favored in wet years, G
roup of answer choices
- hard selection is likely to occur.
- genetic variation is not necessarily maintained.
- rates of fixation are likely to speed up.
- genetic drift will be a stronger force than selection.
- genetic variation is always maintained.
One would think that the part of the population that is not favored in dry years would die and thus reduce the genetic variation but this is not likely to occur, otherwise all the population would die because some individuals would die in wet years and some in dry years. In reality they are able to survive in the transition from dry to humid years or viceversa. Actually, this variability that results from their genetic variability in their adaptability to changes in the climate is what keeps the population alive and able to thrive as time passes.
humans and chimpanzees are different mainly on the significant difference on being able to use speech by humans and not used by chimpanzees. Moreover, humans have such a powerful brain and which provides logics that enable them to carry out more works than any other of their species.
