 In a human population, the gene frequencies of the alleles for the ABO system are as follows:

A = 29%                         B = 7%                                    0=64%

Assuming complete random mating and Hardy-Weinberg equilibrium,

What are the blood type A frequencies in this population?

Gel chromatography is used for hormone separation. A pilot-plant scale gel chromatography column packed with sephacryl resin is used to separate two hormones, A and B. The column is 5 cm in diameter and 30 cm in height: V, = 1.9x 10-⁴m³, Wr = 3x10^-3m³ /kg dry sephacryl, ps =1.25 x 10³ kg/m³ . The partition coefficients are k_pA =0.38 and k_pB= 0.15. If the eluting flow rate is 0.7 I/h, what is the retention time for each hormone?
