Document Summary
Many plants reproduce both sexually and asexually. Through asexual reproduction a plant can reproduce many identical plants quickly and efficiently. More susceptible to environmental changes due to lack of genetic diversity. The great potato famine: crop fails due to oomycete (fungus like) since they were clones, no genetic diversity, potatoes were cultivated and eaten, with left overs given to pigs. You can"t divide an imperfect genome in 2: with triploid, 2 sets don"t have the required doubling. The banana produces asexually, however if a virus comes a long then a lot of the bananas will disappear. The formation of seeds with embryos that are produces without fertilisation (embryos of mother"s clones: ie. They don"t even need to be pollinated, which is why they are so weedy: little microspecies occur due to apomixes. ***the science that names, classifies and determines the evolutionary relationship of living organisms: taxonomy. Consists of identifying, naming and classifying species: phylogeny.
