Answer:

Genetic variation related to a species chances of becoming extinct occurs in such that the most adaptive survives while those otherwise becomes extinct.

Explanation:

According to law of natural selection, the less adaptive organisms becomes extinct as a result of variability in their gene but the ones that quickly adapts becomes more stronger, hence; pass such gene to their younger ones which enables them to survive.

Answer:

Increased genetic variation reduces the species chances of being extinct. Conversely, reduced genetic variation in a species increase the chances of the species being extinct.

Explanation:

With increased genetic variation in a species, there is increased phenotypic variation amongst organisms in the species for natural selection to act on with selection pressures exerted upon the species in their environment e.g. predation or diseases. Hence even if a certain genotype express susceptibility to a certain disease, only some organisms will be selected against and there are sufficient organism without this genotype that will be able to survive and ensure the continuity of the species.

Conversely, if all the organisms express the same genotype susceptible to the disease (in extreme cases), upon exposure to the disease (which acts as the selection pressure), all the organisms will die and there will be no surviving organisms for the continuity of the species. Hence with minimal genetic variation, the species is more prone to extinction due to the inability to withstand selection pressures.

This is often a common cause of concern in the conservation of endangered species. Due to the small number of e.g. tigers remaining, most offsprings are produced through inbreeding between family members thus even though the family tree of the species is expanding, there is little genetic variation within the species. Therefore, the chances of extinction of these endangered species is high and thus biologists and conservationists have to monitor the selection pressures exerted upon these species by their environment to reduce the risk of extinction.

In eukaryotes, how can a single gene code for several different proteins?
NikAS [45]

Answer:

Gene splicing is a post-transcriptional modification in which a single gene can code for multiple proteins. Gene Splicing is done in eukaryotes, prior to mRNA translation, by the differential inclusion or exclusion of regions of pre-mRNA. Gene splicing is an important source of protein diversity.
