I don't know what you mean by your question, but if you are making an appropriate title it will be good if you title it that is unique and would want to make your reader more interested with your story. Just trying to help :)
Answer:
You, a human being and a pet share a mutualistic relationship. A mutualistic relationship is a relationship in which two different species of organisms benefit each other. You and your pet have a mutualistic relationship because a pet provides companionship, comfort, in some cases protection (depending on the pet), and protecting your home from rodents (also depending on the pet). While animals provide these services for humans, in return we provide food, water, shelter, and love/comfort for the animal. Both organisms (you and your pet) benefit from your relationship therefore it is mutualistic.
Answer: A change in allele frequencies caused by random events
Explanation :<u>Genetic drift refers to a process which occur due to sampling error from preceding generations that lead to a change in allele frequency by chance alone within a population.</u> It is a random process which leads to large significant changes within a population over a short period of time. The rapid changes are due to increasing inbreeding coefficient s and homozygosity from the removal of alleles.
It is peculiar to a population which is synonymous with regular cycle of extinction and recolonization. Therefore, together with evolution, mutation and migration, <u>it is one of the driving mechanism of EVOLUTION.</u>
It is caused by;
Static or recurring small population sizes,
"Bottlenecks” form of population, that is drastic reduction in population size;
Repopulation from a small number of individual-FOUNDER EVENTS.
<u>Measurements of Genetic Drift
</u>
The magnitude of genetic drift within a population depends on the effective population size for the population.This is represented as Ne. It is a theoretical number use to quantify the number of genetically distinct individuals that contribute gametes
