Individuals with glucose-6-phosphate dehydrogenase deficiency have increased resistance to malaria because the parasite does not survive well in cells with oxidative stress.
<h3>What is the link between G6P deficiency and malaria?</h3>
- Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked recessive disorder.
- G6PD protects cells from oxidative damage especially the RBCs whose main function is to carry oxygen.
- Mutation in the gene results in G6PD deficiency leading to oxidative stress which can lead to anemia (iron deficiency) as there is breakdown of RBCs.
- However, G6PD deficiency is quite common in parts of Africa, Middle East, and South Asia, which are the regions of high malaria endemism.
- This is due to natural selection in which G6PD deficiency is not eliminated from the population as it can protect people from malaria infection.
- Malaria parasite <em>Plasmodium</em> species does not survive well in cells with oxidative stress.

Answer:
A person can have normal chromosomes in number and structure, but still have a disease or condition caused by a mutation in one or more of the genes on the chromosomes. A single gene defect usually does not cause the chromosome structure or number to be abnormal.
Explanation:
I'm not sure if this is correct but hope it helps.
Identical twins are formed through the process of meiosis where a fertilised egg separates to form two identical cells with a common genetic information.
Fraternal twins on the other hand are developed from the fertilisation of two different eggs and two sperm cells. This type of twins possess unique genetic information.
