You could tell each of the participants to drink a certain amount of coffee (for example: person one drinks 5 oz., person two drinks 7 oz., etc). Then, survey the participants/measure their vitals once every week for a month (or every day if needed) and report about your findings.

Hardy Weinberg Practice Problems To demonstrate your understanding of the Hardy-Weinberg equilibrium, answer each question caref
andriy [413]

Assuming that the affection is a recessive trait caused by a single diallelic gene, the percentage of the population that possess the heter0zyg0us advantage is 32%.

<h3>Available data</h3>

  • 1000 of African people population
  • 4% of the population is born with sickle cell anemia

100% of the population -------------------- 1000 individuals

4% of the population with anemia------- X = (4 x 1000) / 100 = 40

0.04 is the frequency of individuals with sickle cell anemia.

Assuming that the affection is a recessive trait caused by a single diallelic gene, we can get the allelic frequency as follows.

  • The genotypic frequency is q² =  0.04
  • The allelic frequency is q = √0.04 = 0.2

Having the recessive allelic frequency, we can get the dominant allelic frequency, by clearing the following equation,

p + q = 1

p = 1 - q

p = 1 - 0.2

p = 0.8

So, the allelic frequencies are

p = 0.8

q = 0.2

To get the heter0zyg0us frequency, we just need to replace the values

2pq = 2 x p x q = 2 x 0.2 x 0.8 = 0.32

The frequency of the heter0zyg0us genotype is 0.32 = 32%.

32% of the population possess the heterozygous advantage.

Answer:

Amino acids are the building blocks of proteins

There are many possibilities that could happen if the sequence of amino acids were to change. It could potentially create a completely different protein with a different function, or it could create a more efficient protein but this is less likely.
