Answer:
Hello.
• gels can melt during electrophoresis, the buffer can become exhausted, and different forms of genetic material may run in unpredictable forms.
• And the strengths could be that it separates based on size, it is relatively easy to do.
(Assuming that this is about chromosomes)
A male has an XY combination in his chromosomes.
When an area is malaria-free, the HbS allele frequency is between 0 and 2.02. Thus, option "A" is correct.
<h3>How, explain your answer briefly?</h3>
In the two maps that show the allele frequency of sickle haemoglobin (HbS) and malaria endemicity in Africa, it can be seen that in the regions with no malarial outbreak or malaria-free areas coincide with the grey to lighter shades of red in the heat map of the allele frequency of HbS. The colour coding in the heat map for the allele frequency tells us that the frequencies range from 0 to 2.02 in the malaria-free areas.
Hence the answer is A)When an area is malaria-free, the HbS allele frequency is between 0 and 2.02.

Answer:
hey have you gotten the answer, sorry I'm struggling with this question
Answer:
A person with sickle cell trait has one mutated copy of the hemoglobin gene, a person with sickle cell disease has two mutated copies.
Explanation:
Sickle cell disease also known as sickle cell anemia is caused by mutation of the beta chain of hemoglobin, the gene for which lies in 11th number chromosome. If a person possess only one mutated gene, then the disease is not expressed in the person. The person then only possess the trait for sickle cell anemia, that is, there is a chance of sickle cell disease in the offspring, but the sickle cell trait are usually asymptomatic or live like normal individual. While the person possessing two mutated gene is said to be suffering from sickle cell anemia and is found to possess S hemoglobin in the red blood cells which is abnormal hemoglobin without any ability to carry oxygen.
