Imprinting in genetics
Witryna1 wrz 2004 · The PatDp(prox11) imprinting effect potentially attributable to Grb10 appears to operate primarily upon early fetal development, as previously suggested (Cattanach et al. 1992). The MatDp(prox7) imprinting effect appears to operate primarily upon the placenta, as might be expected if Peg3 is the responsible gene. Witryna1 sty 2007 · In a classic article published in Genetics ( Crouse 1960b ), Helen coined the term “chromosome imprinting” when she wrote: “the ‘imprint’ a chromosome bears is unrelated to the genic constitution of the chromosome and is determined only by the sex of the germ line through which the chromosome has been inherited.”
