• Inheritance, in this case, was strictly maternal: a seed derived from an ovule from a non-green stem gave rise to non-green progeny, irrespective of the source of pollen. (nature.com)
  • Mitochondrial DNA (mtDNA) is independent of nuclear DNA (nDNA), and the uniparental, maternal inheritance of mtDNA has been addressed in previous animal studies2. (irjs.info)
  • The homoplasmy that arises from uniparental maternal mtDNA inheritance can be changed experimentally to a heteroplasmic state by oocyte/egg cytoplasmic transfer (CT), in which oocyte cytoplasm containing mitochondria is transferred into another oocyte by microinjection or electrofusion, to study nDNA and mtDNA interactions15,16,17.

  • Non-Mendelian inheritance is any pattern in which traits do not segregate in accordance with Mendel's laws. (wikipedia.org)
  • In Mendelian inheritance, each parent contributes one of two possible alleles for a trait. (wikipedia.org)
  • Non-Mendelian inheritance plays a role in several disease which affected the processes. (wikipedia.org)
  • citation needed] In Mendelian inheritance, genes have only two alleles, such as a and A. Mendel consciously chose pairs of genetic traits, represented by two alleles for his inheritance experiments. (wikipedia.org)
  • citation needed] Genetic traits located on gonosomes sometimes show specific non-Mendelian inheritance patterns. (wikipedia.org)
  • As many of the alleles are dominant or recessive, a true understanding of the principles of Mendelian inheritance is an important requirement to also understand the more complicated inheritance patterns of sex-linked inheritances. (wikipedia.org)
  • Extranuclear inheritance (also known as cytoplasmic inheritance) is a form of non-Mendelian inheritance also first discovered by Carl Correns in 1908. (wikipedia.org)
  • Most heritable information in eukaryotic cells is encoded in the nuclear genome, with inheritance patterns following classic Mendelian segregation. (nature.com)
  • In this review, we examine the diversity and peculiarities of cytoplasmically inherited genomes, and the broad evolutionary consequences that non-Mendelian inheritance brings. (nature.com)
  • Interestingly, cytoplasmic genetic elements have been shown to have very different inheritance patterns to classic Mendelian nuclear chromosomes. (nature.com)
  • The first documented evidence for this came from Carl Correns research on the four o'clock plant Mirabilis jalapa , in which he detailed the non-Mendelian inheritance of leaf colour (Correns 1909 ). (nature.com)
  • These laws describe the inheritance of traits linked to single genes on chromosomes in the nucleus. (wikipedia.org)
  • We summarise the evidence for the adaptive importance of cytoplasmic genes before detailing coadaptation between the cytoplasm and the nucleus, and amongst cytoplasmic components. (nature.com)
  • Intermediate inheritance was first examined by Carl Correns in Mirabilis jalapa used for further genetic experiments. (wikipedia.org)
  • Cytoplasmic genetic elements are generally maternally inherited, although there are several exceptions where these are paternally, biparentally or doubly-uniparentally inherited. (nature.com)
  • Finally, we discuss how both nuclear and cytoplasmic genomes have evolved to co-inhabit the same host cell via one of the longest symbiotic processes, and all the opportunities for intergenomic conflict that arise due to divergence in inheritance patterns. (nature.com)
  • Furthermore, evidence for diversity in inheritance patterns (paternal or biparental) of CIEs started accumulating for a wide range of taxa (Birky 2001 ). (nature.com)
  • We discuss the diversity and patterns of genome organisation for cytoplasmic elements and examine the population genetics of CIEs, highlighting the tension between within- and between-individual spread. (nature.com)
  • Individuals can develop a recessive trait in the phenotype dependent on their sex-for example, colour blindness and haemophilia (see gonosomal inheritances). (wikipedia.org)

  • In this review, we describe the diversity of inheritance systems of CIEs, and highlight the evolutionary consequences that these inheritance systems bring to cellular, organismal and population dynamics (Fig. 1 ). (nature.com)
