Answer: A, Natural selection favors G6PD deficiency as compared to malaria.
Explanation:
We can eliminate B. This is because genetic drifts are changes in genes due to chance. The changes in the genes of the African Americans were not due to chance because there was a cause: malaria.
We can also eliminate C. This is because somatic mutations are mutations that can occur in every cell except the germ cells (sperm, egg), therefore meaning that the mutations that occur cannot be passed onto the offspring.
For the f1 generation. 100% of whichever had the dominant allele.
it will change for the f2 generation
P450scc or cholesterol side chain cleavage enzyme is an enzyme that converts cholesterol into pregnenolone (the precursor for steroids). The kinds of steroid hormones are mineralocorticoids (i.e. aldosterone) glucocorticoids (i.e. cortisol), and sex steroids (i.e. testosterone, estrogen). In the event where P450scc is blocked, then there will be no production of mineralocorticoids, glucocorticoids, and sex steroids. There will be no production of aldosterone, cortisol, estradiol, testosterone, and progesterone. This disease is called Lipoid Congenital Adrenal Hyperplasia.
In any scientific paper you can find th eprocedure part which should in detail explain how the procedure of a particular experiment was performed. Using these instructions we should be able to replicate an experiment, if the results that were obtained in the previoues experiments were correct of course.
It is the trigeminal. check my spelling though.
