What are five conditions that can disrupt genetic equilibrium and cause evolution to occur?

Answer 1

Three ways genetic equilibrium can be disrupted include, mating not being random, mutations occur, and natural selection occurs. Two other disruptions are organisms move in and out of the populations and many populations are too small to begin with.

Answer 2

well i really dod not know but i think is frog

stop cheating on your homework (It's called research, 95% of the teachers rocommend it, your obvously old.)

^^^^^^^ To the person who answered this above:

I recommend you learn how to spell or invest in something called "spell check" because the statement written above is certainly not acceptable.

Oh, really? My bad. I really tried to impress you. dick

Answer 3

the first requirement is that allele frequencies not change overall because of mutations, the second requirement is that the population remain constant,the third requirement is the presence of a large population, the fourth requirement is random matings, and the fifth requirement is the absence of natural selection.

Answer 4

Four possible causes are selective pressure (one genotype being a better fit to the environment), admixture (new members leaving or entering the population), founders effect where population size is not sufficiently large enough, and no random breeding, where mate selection is preferential to certain genotypes choosing each other.

Answer 5

To be sure, there's no such thing as genetic equilibrium, and evolution is continuously occurring: it cannot be prevented. Genetic equilibrium is a theoretical concept used to study the dymamics of single alleles in the population gene pool.

However, there are situations in which the overall morphological makeup of a population is more or less stable - even if the details of that makeup continuously drift. Such a semi-stable situation could be disturbed by any factor: migration; climate change; floods; geological disasters such as volcanic eruptions or earthquakes; the introduction of new prey, new predators, new diseases; the disappearance of prey, predators or diseases; population growth; runaway sexual selection; and so forth, and so on.

Answer 6

1. There must be no genetic drift

2. No gene flow

3. No mutation

4. Mating must be random

5.No natural selection

Answer 7

- Random Mating

- Large Populations

- No movement in or out of population

- No mutations

- No natural selection

Answer 8

mutation, migration, genetic drift

Answer 9
