Because Earth’s field changes over time, geomagnetic imprinting should cause turtles to change their nesting locations as magnetic signatures drift slightly along coastlines. To investigate, we analyzed a 19 ...

Witryna2 lut 2007 · The review addresses the fundamental process of ‘imprinting’. In his classical studies on newly hatched goslings Konrad Lorenz analysed the development of social binding and established the term ‘imprinting’ to describe this process. WitrynaThe imprinted brain hypothesis predicts that Prader-Willi syndrome, a disorder of maternal overimprinting, should have decreased autism and increased …
WitrynaIn conclusion, the genetic conflict hypothesis is very successful in explaining the observed patterns of imprinting for autosomal genes and probably is the most likely evolutionary explanation for them. However, for genes on X chromosomes, other processes of natural selection are more important.

Inherited imprinted genes of offspring are believed to be monoallelic expressions. A single locus will entirely produce one's phenotype although two alleles are inherited. This genotype class is called parental imprinting, … Zobacz więcej Genomic imprinting is an epigenetic phenomenon that causes genes to be expressed or not, depending on whether they are inherited from the mother or the father. Genes can also be partially imprinted. … Zobacz więcej That imprinting might be a feature of mammalian development was suggested in breeding experiments in mice carrying reciprocal chromosomal translocations.
