WebTo summarize, we have just tested a descriptive statement (i.e., a statistical null hypothesis) about an unknown parameter. In this case the statistical null hypothesis is that both probabilities are 0.50. And just like in causal scientific hypothesis testing, we used hypothetico-deductive reasoning to do so. That is: Webhypothesis. A low p value suggests that the data showing deviation from the values predicted by the hypothesis are significant enough to reject the null hypothesis. A p value of 0.001 means that it is highly unlikely (1 chance in a 1000) that the observed distribution of phenotypes arose from two unlinked genes.

"WebIn some cases, the answer is yes. Genes that are sufficiently close together on a chromosome will tend to "stick together," and the versions (alleles) of those genes that are together on a chromosome will tend to be inherited as a pair more often than not.
