Web15. máj 2024 · These have a more phenotypic variation than the ones obtained from monohybrid crosses. The phenotypic ratio of the offsprings in the first generation after a dihybrid cross is written as 9:3:3:1. The genotypes of the offsprings are even more diverse with the ratio of 1:2:2:4:1:2:1:2:1. Gregor Mendel (1822–1884) was an Austrian monk who theorized basic rules of inheritance. From 1858 to 1866, he bred garden peas (Pisum sativum) in his monastery garden and analyzed the offspring of these matings. The garden pea was chosen as an experimental organism because many varieties were available that bred true for qualitative traits and their pollination could be manipulated. The seven variable characteristics Mendel investigated in pea plants were. mashroom texture https://annuitech.com
