  • Crops
  • While the abundance and variation of transgenic organisms in human food systems, and their effect on agricultural biodiversity, ecosystem health and human health is somewhat well documented, mutagenic plants and their role on human food systems is less well known, with one journalist writing "Though poorly known, radiation breeding has produced thousands of useful mutants and a sizable fraction of the world's crops. (wikipedia.org)
  • In Canada crops generated by mutation breeding face the same regulations and testing as crops obtained by genetic engineering. (wikipedia.org)
  • Reports from the US National Academy of Sciences state that there is no scientific justification for regulating genetic engineered crops while not doing so for mutation breeding crops. (wikipedia.org)
  • Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. (wikipedia.org)
  • In contrast to the selective breeding of livestock, arable crops, and horticultural flowers over the last few centuries, the breeding of trees, with the exception of fruit trees, is a relatively recent occurrence. (wikipedia.org)

  • markers
  • Development of SNPs has revolutionized the molecular breeding process as it helps to create dense markers. (wikipedia.org)
  • The basic idea is to identify genes or markers associated with genes that correlate to a phenotypic measurement and that can be used in marker assisted breeding / selection Marker assisted selection or genetic selection Once genes or markers are identified, they can be used for genotyping and selection decisions can be made. (wikipedia.org)
  • animal
  • It can take several weeks to process an evaluation so this should be done well in advance of when you plan to breed the animal. (angelfire.com)
  • Animal Breeding Abstracts is a fully searchable abstracts database of internationally published research into animal production. (cabi.org)

  • Animal Breeding Abstracts is available monthly in print and a typical issue includes approximately 650-700 abstracts with author, subject and citation indexes and a review article. (cabi.org)
  • Ponies of all breeds originally developed mainly from the need for a working animal that could fulfill specific local draft and transportation needs while surviving in harsh environments. (wikipedia.org)
  • Thoroughbred" is a specific breed of horse, while a "purebred" is a horse (or any other animal) with a defined pedigree recognized by a breed registry. (wikipedia.org)
  • However, breeding-back attempts do not always result in an animal that is closer to the wild type than other domestic breeds. (wikipedia.org)

  • 1979
  • Results from this work were published in hardcopy in 2003, and presented detailed distribution maps from the 1974-1979 Breeding Bird Atlas 1 surveys. (massaudubon.org)
  • Breeding got his first professional comics work three months after graduating high school in 1979 as Bob Layton's background assistant. (wikipedia.org)
  • phenotypic
  • Genomic prediction combines marker data with phenotypic and pedigree data (when available) in an attempt to increase the accuracy of the prediction of breeding and genotypic values. (wikipedia.org)
  • reproductive
  • Cooperative breeding causes the reproductive success of all sexually mature adults to be skewed towards one mating pair. (wikipedia.org)
  • This means the reproductive fitness of the group is held within a select few breeding members and helpers have little to no reproductive fitness. (wikipedia.org)
  • The concept behind cooperative breeding is the forfeiting of an individual's reproductive fitness to aid the reproductive success of others. (wikipedia.org)
  • The model is based on the evolution of larger litters forcing the need for helpers to maintain the high reproductive costs, thus leading to cooperative breeding. (wikipedia.org)
  • Tree breeding is the application of genetic, reproductive biology and economics principles to the genetic improvement and management of forest trees. (wikipedia.org)
  • centuries
  • Pace the common notion of eugenics as a phenomenon of the late 19th and early 20th centuries, scholars have now realized that concepts of 'human breeding' or of the 'perfection of the human race' were being developed throughout Western Europe long before Francis Galton, designated the 'founder of the faith' in Kevles's book, published Hereditary Genius in 1869. (ghi-dc.org)
  • thus
  • This result filled the information gap about the UF clones thus will improve their utilization for cacao breeding. (go.jp)
  • Thus a foal conceived in England but foaled in the United States is regarded as being bred in the US. (wikipedia.org)
  • gene
  • Selection strategies have been compared for annual progress in long-term breeding at a given annual cost considering genetic gain, gene diversity, cost components, and time components. (wikipedia.org)
  • bird atlas

  • What is a Breeding Bird Atlas? (massaudubon.org)
  • More than 650 volunteer citizen scientists worked more than 43,000 hours from 2007-2011 to complete the new Massachusetts Breeding Bird Atlas 2. (massaudubon.org)
  • Males
  • Breeding pair arrangements are rare in mammals, where the prevailing patterns are either that the male and female only meet for copulation (e.g. brown bear) or that dominant males have a harem of females (e.g. walrus). (wikipedia.org)
  • cooperative
  • Cooperative breeding is a social system characterized by alloparental care: offspring receive care not only from their parents, but also from additional group members, often called helpers. (wikipedia.org)
  • Many hypotheses have been presented to explain the evolution of cooperative breeding. (wikipedia.org)
  • This concept is hard to understand and the evolution of cooperative breeding is important, but difficult to explain. (wikipedia.org)
  • Group augmentation presents a second hypothesis towards the evolution of cooperative breeding. (wikipedia.org)
  • proposed an evolutionary model for cooperative breeding, which linked the coevolution of polytocy, production of multiple offspring, and monotocy, production of single offspring, with the evolution of cooperative breeding. (wikipedia.org)
  • suggests polytocy may have encouraged the evolution of cooperative breeding. (wikipedia.org)
  • Additionally, they found the transition from polytocy without cooperative breeding to polytocy with cooperative breeding is highly favorable. (wikipedia.org)
  • This suggests cooperative breeding evolved from noncooperative breeding monotocy to cooperative breeding polytocy. (wikipedia.org)
  • Today, there is growing support for the theory that cooperative breeding evolved by means of some form of mutualism or reciprocity. (wikipedia.org)
