Answer:
Allele frequency can be described as a phenomenon which measure how common an allele is in a particular population. It tells about the genes which are richest in a gene pool and it also shows the genetic diversity in a population. Allele frequency is often expressed in percentages.
Natural selection tends to favour those organisms that are best adapted to live in an environment and which can withstand changes occurring in the ecosystem. If due to some circumstances, a trait becomes less useful to organisms in a population then by natural selection the allele frequency for those alleles will reduce with time. Similarly, the alleles which code for better genes for an environmental change will be increased due to the phenomenon of natural selection.
Answer:
Africa needs to urgently put a number of additional measures in place to speed up these advances, and to move towards eliminating the disease. These include accelerated investment and deployment of vaccines, new diagnostic tools, new funding strategies for malaria control and keeping in check the drug and insecticide resistance challenge.
