Using Probability to Solve Complex Genetics Problems

Probability in genetics I | Channels for Pearson

Probability calculation for genetics (from Lindley, 1965 ): suppose that in each individual of a large population there is a pair of genes, each of which can be either x or X, that controls eye color: those with xx have blue eyes, while heterozygotes (those with Xx or xX ) and those with XX have brown eyes. The proportion of blue-eyed individuals is p^2 and of heterozygotes is 2 p(1-p), where 0<p<1. Each parent transmits one of its own genes to the child; if a parent is a heterozygote, the proba
