Autosomal Linkage

Cards (6)

  • In an autosomal linkage... 

    2 or more genes are on the same autosomal chromosome
  • Autosome=

    a chromosome that isn't a sex chromosome
  • Autosomal genes
    = the genes located on the autosomes
  • Genes on the same autosome are said to be ...
    Linked
    • Because they are on the same autosome they will stay together during independent segregation of chromosomes in MEIOSIS I, and their alleles will be passed on to the offspring together
    • HOWEVER THIS WONT HAPPEN IF- crossing over splits them u first (only reason)
  • Closer together two genes are on the autosome=
    the more closely they are said to be linked
    • because crossing over less likely to split them up
  • If two genes are autosomally linked what will you NOT get
    the phenotypic ratio you expect in the offspring of a cross
