Through selective breeding or by natural selection.
It's Selective Breeding! Just found out for school.
Selective breeding or artificial selection.
Artificial selection, also called selective breeding, is a form of human intervention in plant or animal evolution.
Most of the domesticated plants and animals you are familiar with have been produced through selective breeding. Dogs, cats, cows, goats, corn, grass, tomatoes, etc .
Breeding, normally through a process of selection
Artificial selection is anthropogenic -- humans interfere with nature to determine what traits get passed on, whereas natural selection is when through sexual reproduction the traits passed on are determined by survival of the fittest.
Artificial selection interested Darwin because it demonstrated that traits could be modified over generations through selective breeding. This process allowed humans to intentionally choose which traits were passed on to offspring, leading Darwin to realize that a similar natural process could occur in nature, driving evolution through natural selection.
plant breeding means the process of producing new varieties of plants through selection and cultivation. hybridization means the union of the male gametes from a particular species with the female gamete belonging to another species to produce a new zygote. by Gougin chongloi
Through tomatoes!!!!
In selective breeding the owners of the pets will choose mates that have selected characteristics that are wanted in the offspring. They may also be repeated with future offspring. In natural breeding it is natural selection that choose and in cats their may even be more than one father and different offspring. In summary the main differences are: Selective humans choose partners with named specific characteristics where as natural if often more first come first served. Also selective breeding is often carried on through the generations whereas natural does not. Similarities are after partners are choose the rest of the process is the same.
Most of the ornamental and cultivated plants have resulted by selection of superior genotypes over the years. The skill of the gardeners to have better plants for gardening have been achieved through plant breeding.
