Question
thumb_up100%
DNA typing is used to compare evidence DNA (E) left at a crime scene to two suspects
(S1 and S2). Suspect 1 is excluded by the evidence, but suspect 2 remains included. What is
the frequency of suspect 2's genotype if the allelic frequencies in the population are f(A1) =
0.1, f(A2) = 0.2, and f(A3) = 0.7, and the population is at Hardy–Weinberg equilibrium?
I do not need the answer, just HOW you do it. I got 0.02 as the answer, but I know that isn't right.

- Once upon a time there was a population of hippies living in an isolated commune called Gone. They had been there for generations, and all members were homozygous for a gene that gave them a preference for crafting necklaces out of green beads, so that every individual had the genotype GG at this locus. In another isolated commune, called Yonder, was a population of hippies that had a genetic propensity for making necklaces out of yellow beads, and everyone was homozygous for a different allele at the same genetic locus; their genotype was YY. Last year (prior to our current social isolating) everyone repaired their VW buses, and a giant gathering in celebration of the 50th anniversary was held at the Oregon Country Fair. The next few questions will ask you about these two populations that came together at the fair.arrow_forwardheritability was published in 2009 in the International Journal of Obesity. This study uses data from the "FinnTwin16" study in which nearly all twins born in Finland from 1975-79 are being tracked for many phenotypes. The table below reports correlation coefficients (rmz and dmz) separately for male and female twin pairs at about 30 years of age for 3 traits: BMI, waist circumference, and level of physical activity (the study investigated the relationships between these traits). Calculate H² for each trait and sex using the strategy discussed in Video 4.4. Match the your values with the appropriate trait and sex.
