What is the interpretation of the equation p + q + r = 1.0?

only 3 alleles can exist in any population

the sum of the relevant individual alleles in a population is equal to 100 percent of those alleles

the probability of sampling all three alleles from a population is 1

there are high levels of inbreeding in the population

mutation rates are high in the population

Answer #1

1. Answer: Option B is correct
Explanation:
H-W equilibrium for a 3-allele system:
p+q+r = 1
p2 + q2 + r2 + 2pq + 2qr + 2pr = 1

Conditions:
1. No mutation
2. No migration
3. No selection
4. Random mating
5. Large population

There CAN be more than three alleles in a given population at a given time.
p+q+r = 1
It only signifies that there are three alleles in the given population at the given time i.e. only 3 alleles exist at that particular time for the given population.
If only 3 alleles exist, the sum of all three alleles = 1

) Imagine that you are a grad student in Biological Anthropology, and you travel to the land of “Jenesaiquoivia” to study Jenesaiquoivian genetics. [Footnote 1] You notice that 9 out of every 100 people in your study group have blue eyes. The rest of the population have brown eyes. You know that the brown eyes allele is dominant, and blue eyes is recessive. [2] Construct the Hardy-Weinberg equation for that population. You know that q2=.09 (9%) so p2 plus 2pq...
