Employees are entitled to their final paycheck, in due time. Comstock/Comstock/Getty Images. An expired payroll check can create a financial accounting problem for any company. Companies may have to account for expired checks because employees fail to pick them up or fail to cash the check. Employers have various options for dealing with a final or stale paycheck, but once the check expires it creates additional work for the payroll department.
allele frequency. The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.
Start with the known genotype, bb. It makes up 0.25 of the population, the frequency of the b allele is sqrt(0.25) = 0.5. If the frequency of b = 0.5, then the frequency of B is 1-0.5 = 0.5. Using the H-W equations, q = 0.5 and p = 1 - q = 0.5.Equation #2, pâ2 + 2pq + qâ2 = 1 becomes 0.25 + 0.5 + 0.25 = 1.ince you know that q^2 = 25/100 = 0.25, just take the square root to find the allele frequency of q. (q^2)^1/2 = 0.5 Lastly, since p + q = 1 always, the frequency of the dominant allele p is 1 - q = 1 -.5 = 0.5. Source(s): green_commander Â· 5 years ago.
