In Europe, 1 albino is found for every 10,000 people with normal melanin levels. The albinism gene is inherited in an autosomal recessive manner. Calculate the frequency of occurrence of carriers of the albinism gene. A carrier is an organism that is heterozygous for a gene that can cause a metabolic disorder in a homozygous state.

g2 (aa) = 1 / 10,000
g (a) = √1 / 10,000 = 0.01
p (A) = 1- 0.01 = 0.99
then the frequency of heterozygotes 2рg (Aa) = 2 * 0.99 * 0.01 = 0.0198 or almost 2%, that is, there is 1 carrier of the albinism gene per 50 people.
10000-100%
X – 2%
x = 200 people They are heterozygous for the albinism gene.
Then 10000: 200 = 50, i.e. there is 1 albino for every 50 people.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
