RFLP analysis of some blood from a crime scene shows that the blood belongs to someone with genotype D1/D3, E2/E5, F5/F5, G1/G3. the frequencies of these genotypes in the Caucasian population are D1/D3 =0.01, E2/E5= 0.02, F5/F5= 0.001, G1/G3= 0.00001. What proportion of the Caucasian population shares this genotype with this person.
a. 0.0311
b. 0.0001
c. 0.00005
d. 0.000001
e. 2 * 10^-11
i need the same exact question for my ap bio take home test too!
omg gurrrll you know i need that asian answer now! telll me telll me telll me or i will throw egg rolls at you now.
guys im really depressed. i need this answer too
To find the proportion of the Caucasian population that shares this genotype with the person in question, we need to multiply the frequencies of each genotype together.
Given that the frequencies of the genotypes are:
D1/D3 = 0.01
E2/E5 = 0.02
F5/F5 = 0.001
G1/G3 = 0.00001
We can calculate the proportion as follows:
Proportion = (Frequency of D1/D3) * (Frequency of E2/E5) * (Frequency of F5/F5) * (Frequency of G1/G3)
Proportion = 0.01 * 0.02 * 0.001 * 0.00001
Proportion = 0.00000000002
This value can be expressed as 2 * 10^-11.
Therefore, the correct answer is option e. 2 * 10^-11.
