Brassica oleracea was a European wild plant. Early farmers were able to use artificial selection on this plant to produce cabbag
e, Brussels sprouts, kohlrabi, kale, broccoli, and cauliflower. This diversification through selection was possible because: a. artificial selection is always possible, whereas natural selection requires much larger population sizes.
b. artificial selection does not require differential reproductive success, whereas natural selection does.
c. the species contained large amounts of genetic variation.
d. artificial selection is only done on plants that are used for food, whereas natural selection is used on all other plants.
e. exotic species are always more adaptable than the native species in an area.
Artificial selection is also known as selective breeding is the process where particular traits are selected by humans for sexual reproduction.
This was a method used in animal and plant breeding.
Early farmers were able to use this method of diversification to produce cabbages and other vegetables because these species contained a large amount of variation.
There was a large variety of trait to choose from.
