The time required to reach 1.5 kg (3 lb 5 oz) live-weight decreased from 120 days to 30 days between 1925 and 2005. Selection for fast early growth-rate, and feeding and management procedures to support such growth, have led to various welfare problems in modern broiler strains. [1]
Additionally, the effects of density-dependent processes, epistasis, and soft selective sweeps on the maximum rate of substitution have been examined. [ 12 ] By looking at the polymorphisms within species and divergence between species an estimate can be obtained for the fraction of substitutions that occur due to selection.
The Gros Michel has a higher concentration of isoamyl acetate, the ester commonly used for "banana" food flavoring, than the Cavendish. [12] This higher concentration is responsible for the myth that banana flavoring was based on the Gros Michel, but artificial banana flavor was not based on any specific cultivar. [13]
Leading cause of death (2016) (world) The following is a list of the causes of human deaths worldwide for different years arranged by their associated mortality rates. In 2002, there were about 57 million deaths.
A microprobability is a one-in-a million chance of some event; thus, a micromort is the microprobability of death. The micromort concept was introduced by Ronald A. Howard who pioneered the modern practice of decision analysis. [3] Micromorts for future activities can only be rough assessments, as specific circumstances will always have an impact.
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.
It is the banana spider’s doppelganger, the Brazilian Wandering Spider, that was named the most venomous animal in 2007 by the Guinness Book of World Records. To tell the two apart, take a ...
These characteristics become increasingly well developed in successive generations. Artificial selection was successful long before science discovered the genetic basis. Examples of artificial selection include dog breeding, genetically modified food, flower breeding, and the cultivation of foods such as wild cabbage, [168] and others ...
