G6pd deficiency is an inherited condition in which the body doesn't have enough of the enzyme glucose-6-phosphate dehydrogenase, or g6pd, which red blood cells (rbcs) function normally. g6pd deficiency is most common in african-american males. many females are carriers. it is known that africa and the mediterranean basin are high-risk areas for the infectious disease malaria. researchers have found evidence that the parasite that causes malaria does not survive well in g6pd-deficient cells. how can you explain this?

natural selection favors g6pd deficiency as compared to malaria.

genetic drift is responsible for greater occurrence of g6pd deficiency in these regions.

somatic mutations lead to g6pd deficiency in malaria-inflicted regions.

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:
