Linked genes

Which genes are linked?

  • bl and D
    In literature I've found different recombination frequencies:
    Author Rec. freq.
    Beckmann (1966)
    Beckmann (1989)    		 16%*
    Dr. Duncker, cited by Vins (1983) 12%**
    (*) Beckmann uses 16% as recombination frequency in his calculations, but he says (translation from Dutch): "This chance is called the crossing-over percentage, and with the factors b+ and D+ this is about 14%"
    (**) Vins mentions the results (107 young) of different pairings used to calculate the recombination frequency. Unfortunatly he made a mistake in the calculations and talks about a recombination frequency of 13%. Furthermore, a sample size of 107 is statistically to small to make an accurate estimate.
  • The genes on the sex chromosomes:
    • op: opaline
    • cin: cinnamon
    • ino: ino, texas clearbody
    • sl: slate
    This would be the order of the genes and the recombination frequencies: op-30%-ino-3%-cin-7%-sl
