The dihybrid cross was the way he established his second law of heredity: the principle of independent assortment
. Mendel, of course, didn't call his box a "Punnett Square," since this wasn't developed until later.
He was dealing with the Peas plants and worked out two laws of inheritance including Mendel's law of segregation and the law of independent assortment
which are being very famous and strongly accepted in the scientific community now a days as well.
The two organizations will maintain separate branding and independent assortment
planning and merchandising.
The module was broken up into four sections; the first covered the Law of Dominance, the second and third covered the Law of Segregation and Law of Independent Assortment
, and the last the Drosophila Fly Lab.
Chi-squared tests will be performed to determine if the observed number of plants with a particular phenotype equals the expected for independent assortment
indicating whether or not the gps loci is linked to that particular trait.
