  2. Inbreeding - Wikipedia

    en.wikipedia.org/wiki/Inbreeding

    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.

  3. Inbreeding avoidance - Wikipedia

    en.wikipedia.org/wiki/Inbreeding_avoidance

    However, inbreeding also gives opportunity for genetic purging of deleterious alleles that otherwise would continue to exist in population and could potentially increase in frequency over time. Another possible negative effect of inbreeding is weakened immune system due to less diverse immunity alleles as a result of outbreeding depression. [6]

  4. Genetic purging - Wikipedia

    en.wikipedia.org/wiki/Genetic_purging

    Genetic purging is the increased pressure of natural selection against deleterious alleles prompted by inbreeding. [1]Purging occurs because deleterious alleles tend to be recessive, which means that they only express all their harmful effects when they are present in the two copies of the individual (i.e., in homozygosis).

  5. Habitat fragmentation - Wikipedia

    en.wikipedia.org/wiki/Habitat_fragmentation

    Inbreeding does not always result in negative fitness consequences, but when inbreeding is associated with fitness reduction it is called inbreeding depression. Inbreeding becomes of increasing concern as the level of homozygosity increases, facilitating the expression of deleterious alleles that reduce the fitness. Habitat fragmentation can ...

  6. Genetic viability - Wikipedia

    en.wikipedia.org/wiki/Genetic_viability

    [1] [2] The term is generally used to mean the chance or ability of a population to avoid the problems of inbreeding. [1] Less commonly genetic viability can also be used in respect to a single cell or on an individual level. [1] Inbreeding depletes heterozygosity of the genome, meaning there is a greater chance of identical alleles at a locus. [1]

  7. Genetic erosion - Wikipedia

    en.wikipedia.org/wiki/Genetic_erosion

    Genetic erosion in agricultural and livestock is the loss of biological genetic diversity – including the loss of individual genes, and the loss of particular recombinants of genes (or gene complexes) – such as those manifested in locally adapted landraces of domesticated animals or plants that have become adapted to the natural environment in which they originated.

  8. Captive breeding - Wikipedia

    en.wikipedia.org/wiki/Captive_breeding

    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 ...

  9. Mealworm - Wikipedia

    en.wikipedia.org/wiki/Mealworm

    A study found that the effects of nutritional imbalance on body composition were buffered by the subsequent selection of complementary foods. This demonstrates that the mealworm beetles are capable of compensating for nutritional imbalances and that the way nutritional balance is restored depends on the nutrient that is initially deficient in ...
