Calculate the frequency of carriers of the recessive allele of the gene that causes diabetes if it is known that the disease occurs with a frequency of 1 in 200.
g (aa) = 1/200 g (a) = √1 / 200 = 0.07 p (A) = 1-0.07 = 0.93
means the frequency of heterozygotes 2рg (Aa) = 2 * 0.93 * 0.07 = 0.13 or 13%
200 people – 100%
X people – 13%
x = 26 people
They are carriers of the recessive gene that causes diabetes.
Frequency of heterozygous genotype 200: 26 = 7.7
Answer: frequency of heterozygous genotype 1 to 7.7
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.
