Inbreeding depression in Delphinium nelsonii. A. Overall fitness of progeny cohorts and the B. progeny lifespan were all lower when progeny were the result of crosses with pollen taken close to a receptor plant. [1] Inbreeding depression is the reduced biological fitness that has the potential to result from inbreeding (the breeding of related ...
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.
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).
Things got so bad they had to resuscitate her, so when we got there a few days later, she was still looking horrible. When she was changing his diaper, I could tell she had never changed a baby ...
Inbreeding avoidance, or the inbreeding avoidance hypothesis, is a concept in evolutionary biology that refers to the prevention of the deleterious effects of ...
Thank you @genesis_band for the memories, thank you dad for being such an inspiration and thank you @nic_collins for making me the proudest sister there is. 50 years of songs later and still ...
Though there are many traits about zebrafish that are worthwhile to study including their regeneration, there are relatively few inbred strains of zebrafish possibly because they experience greater effects from inbreeding depression than mice or Medaka fish, but it is unclear if the effects of inbreeding can be overcome so an isogenic strain ...
