Mendel’s Principles The Principle of Segregation says that in diploid organisms genes come in pairs and that when gametes get produced, each gamete gets one gene at random. The Principle of Independent Assortment states that the behavior of one pair of alleles is independent of the behavior of any other pair of alleles.

Unformatted text preview: outcomes of genotypes when more than one type of gamete is produced P generation is the parental generation A cross between P generation yields an F1 generation. An F1 generation yields an F2 generation and so on. . Monohybrid Cross Involves only one trait Heterozygous Dihybrid Cross AaBb X AaBb This will yield a 9:3:3:1 phenotypic ratio Chi-square Analysis A statistical test used to compare observed data with data that we would expect to obtain according to a specific hypothesis. We test the null hypothesis, which states that there is no significant difference between the expected and the observed results. The formula for chi-square is : 2 = (d 2 /e)...
