The Population Reference Bureau (PRB) Country ranking and comparison by TFR: 1970 and 2013 list is sourced and based on the data of the 2014 World Population Data Sheet, [16] which was published online. [17] [18] Forecast/prediction ranking lists: The UN ranking list is sourced from the United Nations World Population Prospects. Figures are ...
Inbreeding is also used to reveal deleterious recessive alleles, which can then be eliminated through assortative breeding or through culling. In plant breeding, inbred lines are used as stocks for the creation of hybrid lines to make use of the effects of heterosis. Inbreeding in plants also occurs naturally in the form of self-pollination.
A 2023 map of countries by fertility rate. Blue indicates negative fertility rates. Red indicates positive rates. The total fertility rate (TFR) of a population is the average number of children that are born to a woman over her lifetime, if they were to experience the exact current age-specific fertility rates (ASFRs) through their lifetime, and they were to live from birth until the end of ...
Country Number of births (2023) India 23,219,489 China 8,899,881 Nigeria 7,509,758 Pakistan 6,882,058 Indonesia 4,482,359 Democratic Republic of the Congo 4,369,683
The article lists 233 countries and territories in crude birth rate. The first list is provided by Population Reference Bureau. [1] The second list is based on CIA World Factbook estimates for the year 2023. [2] Dependent territories and not fully recognized states might not be ranked.
The detrimental effects of inbreeding depression are especially prevalent in smaller populations and can therefore be extensive in captive populations. [19] To make these populations the most viable, it is important to monitor and reduce the effects of deleterious allele expression caused by inbreeding depression and to restore genetic ...
"The period before World War I led to the initiation of inbreeding in rats by Dr Helen King in about 1909 and in mice by Dr C. C. Little in 1909. The latter project led to the development of the DBA strain of mice, now widely distributed as the two major sub-strains DBA/1 and DBA/2, which were separated in 1929-1930.
Svante Pääbo, Nobel Prize laureate and one of the researchers who published the first sequence of the Neanderthal genome.. On 7 May 2010, following the genome sequencing of three Vindija Neanderthals, a draft sequence of the Neanderthal genome was published and revealed that Neanderthals shared more alleles with Eurasian populations (e.g. French, Han Chinese, and Papua New Guinean) than with ...
