<h3><u>Answer;</u></h3>
When an area is holoendemic, the HbS allele frequency is between 0.52 and 4.04.
<h3><u>Explanation;</u></h3>
- <em><u>HbS allele is the sickle cell hemoglobin allele that provides immunity to malaria. This is because people with the sickle cell allele have a selective advantage in areas where there is a high incidence of malaria.</u></em>
- Therefore, natural selection will favor the population with HbS allele in a Malaria holoendemic (most individuals are infected) region. The HbS allele frequency in this population is expected to be high.
- After malaria is cured, the frequency of the HbS allele should decrease in regions with a lot of mosquitoes because having one copy of the HbS allele will no longer be advantageous in these regions.
<span>If
the population is separated long enough, this means that random sampling in mating
and reproduction, that occurred in the
initial population has been restricted</span><span>. The two population will, therefore, adapt to
their local environments and become reproductively isolated
with time. After long periods of time, the two lizards population will have different
alleles and will not be able to mate and
produce viable offsprings hence will have
speciated.</span>
Water is not a living thing because it is not made up of a living atomic structure, water is instead made up of 2 hydrogen atoms and 1 oxygen atom unlike other living creatures.
