Description

This lesson predicts genetic probability using monohybrid and
dihybrid Punnett Squares. In 1905, Reginald Punnett, devised a
short-hand way of determining the expected proportions of possible
genotypes in the offspring of a cross. This method is called the
Punnett Square. It takes account of the fact that fertilization
occurs at random, as Mendel's Law of segregation states. If the
genotypes of the parents are know a Punnett Square can be used to
predict the possible genotypes of offspring.
