Consider an advantageous allele segregating in a population as a major polymorphism. Which of the following would not generally
slow the fixation of the allele? a. The environment changes in such a manner as to reduce the selective advantage.
b. The population begins to receive immigrants from a population that maintains the same initial frequency of the alleles.
c. In addition to being advantageous the allele also exhibits overdominance.
d. The population begins to exhibit positive assortative mating for each of the genotypes.
e. The population size increases.
C. In addition to being advantageous the allele also exhibits overdominance.
Explanation:
If the allele is advantageous and dominant over the other alleles, the individuals who own it will adapt better to the environment and most of their offspring will exhibit the attributes granted by the allele, which would increase its frequency in the population over time. In addition, individuals who own it will be more successful and more likely to reproduce than those who do not.
They are an invasive species, they kill off our beautiful salmon and other fish that we need to keep a good flow of fish exports and money flowing into our state. It's important to keep that balance so that both the pray and they predator in the lakes don't all die out.
S waves are more dangerous than P waves because they have greater amplitude and produce vertical and horizontal motion of the ground surface. The slowest waves, surface waves, arrive last. They travel only along the surface of the Earth. There are two types of surface waves: Love and Rayleigh waves.
