    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.

    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
