Important Properties of Ideal Markers For MAS

An ideal marker:

  • Easy recognition of all possible phenotypes (homo- and heterozygotes) from all different alleles
  • Demonstrates measurable differences in expression between trait types and/or gene of interest alleles, early in the development of the organism
  • Has no effect on the trait of interest that varies depending on the allele at the marker loci
  • Low or null interaction among the markers allowing the use of many at the same time in a segregating population
  • Abundant in number
  • Polymorphic

Famous quotes containing the words important, properties and/or ideal:

    The discovery of the North Pole is one of those realities which could not be avoided. It is the wages which human perseverance pays itself when it thinks that something is taking too long. The world needed a discoverer of the North Pole, and in all areas of social activity, merit was less important here than opportunity.
    Karl Kraus (1874–1936)

    The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.
    John Locke (1632–1704)

    We have reason to be grateful for celestial phenomena, for they chiefly answer to the ideal in man.
    Henry David Thoreau (1817–1862)
