If genetic drift is occurring you will be able to predict which allele will become more prevalent.
Blizzard [7]

Answer:

b. False

Explanation:

Genetic drift corresponds to a drastic casual alteration of the natural order, reaching the genotypic concentration of one or several species, not preliminarily involving natural selection factors, but caused by sudden events. As happens at random, it is impossible to predict which allele will be prevalent in a population suffering from genetic drift.

Such phenomenon is characterized by the occurrence of ecological catastrophes, for example: earthquakes, tsunamis, tornadoes, floods, burnings, avalanches and other processes, affecting a large population contingent.

Thus limiting the genetic content of a particular group, restricted to the prevailing individuals. It is up to them, integration into another population, if an adaptation is maintained, or over time, from geographic and later reproductive isolation, constitution of a new species (principle of the founding species).

In this situation, with low variability, differentiated individuals will experience a more significant selection pressure in relation to the ascending lineage, which minimized the achievements of selection due to the high number of living individuals.

During evolution, a hypothesis concerning the decimation of dinosaurs, which occurred around 66 million years ago, establishes not only the end of these animals, but of various life forms (including plants), due to a huge asteroid that would have reached planet, raising a dense cloud of dust resulting from the collision, compromising photosynthetic processes (dependent on solar energy), as well as the respiration and nutrition of organisms.
