Quantitative inheritance involving several genes all producing identical effects can create a variety of phenotypes which have different survival capacities in a given environment. Clearly the optimal genotype will be present in maximum numbers with the less successful genotypes present in rarer frequency. If the optimal genotype is in the center of the range, then the population curve describes a normal distribution. If the optimum lies toward the maximum or minimum number of genes however, then the maximum genotype is skewed either toward the maximum or minimum and the geneticist is dealing with a Poisson distribution. The programs in this section of the stack permit one to analyse a data spread on the basis of either a normal or poisson distribution. The coin toss is simply an example of how a random process advances and how many trials might be required before a statistically significant number are attained. The chi square program provides you with the probability of how often an experimentally observed data spread might be expected to appear if a given hypothesis explaining the data is true.
