Question

The population of a region is 100 000. There are 250 albinos in the region. The estimated number of normal person carrying albino gene is:
a. 5900
b. 9500
c. 95000
d.59000
e. 159000

Answer 1

To answer this you need background info on the type of albinoism. Is it a single gene? Is it dom or res? Have to know to answer.

Answer 2

Assuming the type of albinoism is ressesive and monogenic, which it almost always is.
Assuming the population is at hardy-weinberg equilibrium, which you need to answer the question.

q^2+2pq+p^2=1 (the hardy-weinberg equilibrium)
Where q^2 is the number of people with albinism, 2pq is the number of people heterozygotic for the trait and p^2 is the number of homozygotes for the healthy gene.

Where q^2=250/100000=0.0025
q=0.05
p=1-0.05=0.95
2pq=2*0.05*0.95=0.095
0.0475*100 000=9500

Answer 3

So the answer is b
