Answer:
<em>The correct option is a) non disjunction</em>
Explanation:
Non disjunction can be described as one of the most common times of errors of the chromosome. Due to non-disjunction, the chromosomes are not able to separate properly at the time of the division of the cell. As a result, sex cells containing the wrong number of chromosomes are made. This leads to various disorders in the offsprings being formed. Hence, the correct option is a) non disjuction.
Endangered species with very small populations are especially at risk of loss of genetic diversity due to option(d) i.e, genetic drift.
A species that is threatened with extinction in the near future, either globally or within a certain political jurisdiction, is known as an endangered species. Invasive species, habitat degradation, poaching, and other issues may put endangered animals in danger.
Genetic drift is the arbitrary change in the frequency of a gene variant in a population. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity. Additionally, it has the potential to make previously uncommon alleles far more common and even fixed. Drift lowers genetic diversity in populations, which may limit a population's capacity to adapt to new selective pressures. In smaller populations, genetic drift is more pronounced and has more severe consequences. Particularly in the case of rare and endangered species, this effect is significant.
The complete question is:
Endangered species with very small populations are especially at risk of loss of genetic diversity due to:
immigration.
mutation.
natural selection.
genetic drift.

Answer:
For competition to exist within a population or between population, shared or common resources that organisms holds very important must be very limited and scared. Competition is a struggle between organisms for limited resources in the ecosystem.
