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?

Answer:

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.

  • C/C Genotype:

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.

  • T/T Genotype:

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.

Imagine that you are studying alien life-forms discovered on a distant planet. While geneticists are working out the genetic cod
34kurt

A phylogenetic tree based on morphology can be constructed using the presence or lack of characteristics. In this illustration, all aliens except the outgroup possess a spring tail, all aliens possess a fourth eye, two aliens possess two tails, and one alien has a grasping hand. The evolutionary relationships between these organisms can be hypothesized using these traits.

Aliens:

  • We can determine whether the following traits are present in the remaining aliens by using the group of aliens with the tail stalk as our test group.
  • Out group: a group that is maintained apart from the clade but is yet connected to it.
  • If we provide these aliens alphabets for ease of understanding, then aliens will be like in order.
  • We can use the group of aliens with the tail stalk as our test group to see if the following characteristics are present in the remaining aliens.
  • A group that is kept separate from the clade while yet being affiliated with it is known as an out group.
  • The aliens will appear to be in order if we give them alphabets for simplicity.
