Answer:
The evolutionary mechanism that could be influencing the allele frequencies between both islands and the mainland population might be Founder Effect.
Explanation:
Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time and eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster -bottleneck effect- or because of a population split -founder effect-. In <u>founder effect</u>, a new population originates when a few individuals who are coming from a bigger population carrying its genes, settle down in a new area and reproduce. This small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be completely lost. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, <u>genetic variability is reduced</u> and there exists the possibility of developing a peculiar allelic composition. If the number of individuals that originated the new population is low, the founder effect will be very extreme, because the effects of the genetic drift are inversely proportional to the original number of individuals.
<em>In the exposed situation, the evolutionary mechanism that could be influencing the allele frequencies between both islands and the mainland population might be Founder Effect. The fact that both islands are similar in their frequencies might be due to little genetic variation on island 1, or because dispersion to island 2 is a recent event on time. </em>
viruses are tiny bundles of genetic material which is carried in a viral coat.
<u>Explanation:</u>
- The virus is generally a parasite that needs a host to become active and to reproduce. It cannot reproduce without the host.
- The tiny bundle consists of genetic material and protein. The virus consists of capsid and nucleic acid. This capsid is said to be the protein coat.
- This capsid consists of either RNA or DNA. virus replicate themself within the host body by using its genetic material along with the mechanism of the host.
- Thus after replicating the virus need to get out of host cell, It is performed by two types budding or lysis( bursting the host cell ).
Answer:
Donor coordination is meant to counteract this and has become an important item on the international development agenda.The underlying reason for this is the growing pressure to improve the efficiency and effectiveness of development cooperation exerted, on the one hand, by the ambitious Millennium Development Goals (MDGs) and the comprehensive poverty reduction strategies being pursued by many low-income countries and, on the other hand, by scarce development cooperation resources.
Explanation:
I think its B.all the members of a population ate genetically very similar etc
Humans have approximately 24,000 genes, but fruit flies are not far behind, with approximately 14,000 genes.
