Triploids are usually autopolyploids. They arise spontaneously in nature, but they can be constructed by geneticists from the cross of a 4n (tetraploid) and a 2n (diploid). Triploids are characteristically sterile due to

 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?
