The existence of limits in artificial selection experiments was discussed in the scientific literature in the 1940s or earlier. [1] The most obvious possible cause of reaching a limit (or plateau) when a population is under continued directional selection is that all of the additive-genetic variation (see additive genetic effects) related to that trait gets "used up" or fixed. [2]
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
Domestication of plants is an artificial selection process conducted by humans to produce plants that have more desirable traits than wild plants, and which renders them dependent on artificial usually enhanced environments for their continued existence. The practice is estimated to date back 9,000–11,000 years.
[3]: 357 In general, two types of experiments have been conducted: using artificial selection to mimic natural selection that eliminates the hybrids (often called "destroy-the-hybrids"), and using disruptive selection to select for a trait (regardless of its function in sexual reproduction).
Human-directed genetic manipulation began with the domestication of plants and animals through artificial selection in about 12,000 BC. [1]: 1 Various techniques were developed to aid in breeding and selection. Hybridization was one way rapid changes in an organism's genetic makeup could be introduced. Crop hybridization most likely first ...
It has been suggested that M. acuminata may have originally been domesticated for parts other than the fruit. Either for fiber, for construction materials, or for its edible male bud. [ 25 ] They were selected early for parthenocarpy and seed sterility in their fruits, a process that might have taken thousands of years.
Bananas are a naturally sweet tropical fruit that goes well with everything from smoothies to oatmeal to desserts. However, their inherent sweetness comes from natural sugar, also known as carbs.
We Have No Bananas", a novelty song about a grocer from the 1922 Broadway revue Make It Snappy, is said to have been inspired by a shortage of Gros Michel bananas, which began with the infestation of Panama disease early in the 20th century.
