Coin tosses can demonstrate the effects of genetic drift. Imagine that heads and tails are two alleles in a population. Consider

each coin toss to represent a member of the population. What describes the effect that you see here?

Answer:

Smaller populations have a greater chance of having one allele expressed disproportionately.

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.  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.

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. In this scenario, smaller populations will have a greater chance of having a disproportionately expressed allele as the number of members is reduced. We can also see this effect if by using a coin we imagine that heads and tails are two alleles in a population and each coin toss represents one member of that population.

Answer:

It develops over land and is cold and dry!

Explanation:

It's a continental air mass, so it develops over land! Maritime ones develop over water. It's cold and dry because it's a polar air mass, not tropical!

<span>This is an example of convergent evolution. These animals gained these similar antler structures to be able to survive in similar environments. Convergent evolution gives organisms who are unrelated similar characteristics as they evolve. The characteristics are influenced by the organism's similar habitats and are given to them to make sure the organisms are able to adapt to survive.</span>

Evolutionary biologists have observed variation in the average age and size of mature individuals in a population of small fresh
Molodets [167]

Answer:

C. After many generations, the offspring of the introduced guppies with mature at an older age and larger size because of selective pressure from the new predator.

Explanation:

In the above scenario evolutionary biologists found variation in guppies with average age and size due to selective pressure from the predators including pike cichlids and killifish. As cichlids preys larger guppies primarily and killifish preys smaller guppies but with killifish, it has been found that guppies reproduced at older age and larger at maturity.

So, because of selective pressure, the new generation of guppies will be mature at an older age with increase in size.
