Suppose that we study a gene that has been linked to coronary heart disease. We find in a pilot study that in subjects with the C/ C genotype 20 events have occurred in 200 individuals over a period of 10 years, whereas in subjects with the T/ T genotype 30 events have occurred in 250 individuals in 10 years. Which genotype appears to be associated with a higher prevalence of heart disease?

T/ T genotype

Explanation:

To know which genotype appears to be associated with a higher prevalence of heart disease, you must know which genotype appeared in the highest percentage in the population tested.

For this, we will do the following calculations.

200 people = 100%

20 people = X

X = (20 * 100) / 200

X = 10%

This means that the C/C genotype appeared in 10% of the tested population.

Now we must to know the percentage of the T / T genotype, we must consider 200 of the 250 people tested.

250 people = 100%

200 people = x

X = (200 * 100) / 250

X = 80%

200 people = 80%

30 people = X

X = (30 * 80) / 200

X = 12%

Thus, we can say that the T / T genotype appeared in a higher percentage within the tested population, being considered the genotype that seems to be associated with a higher prevalence of heart disease.

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
