| Abstract: | There were four plane geometric figures, such as right triangles, diagonal lines, Paralle lines and points in the tabel of Mendels laws of segregation and independent assortment. The algebraic expressions of the right triangles, diagonal lines and paralle lines were 2 n-1 , 2, 4(2 n-1 -1), respectively. The domain of the function was n≥1 (n is the number of relative character of parents ). Those results showed that, the number of genetype, phenotype, heterogeneity degree and segregation ration of F_2 could be expressed by geometric figures. |
