Gregor mendel question? 10 points gets the right anwser!?
prevent cross pollination
Reply:Ah, the father of modern genetics. Perhaps it was to experiment with different plants in a selective way. For example, if the male part is missing, the plant cannot fertilize itself. This way, he can interbreed plants of different colors or leaf-types and can be selective about it to see which color, for example, is dominant.
Reply:To prevent self fertilization and experiment with cross fertilization. For example, he wondered: "What if I cross fertilize a purple flower with a white one...? Thus giving birth to the term hybrids or the offspring of 2 different varieties. ;)
Reply:small bags over flowers prevented cross-pollination; immature stamens==== could be removed to prevent self-pollination==== to insure the parentage of new seeds
