Molecular Imprinting - an overview ScienceDirect Topics

WitrynaSocial scientists follow the "imprint hypothesis" of generations (i.e., that major historical events — such as the Vietnam War, the September 11 attacks, the COVID-19 pandemic, etc. — leave an "imprint" on the generation experiencing them at a young age), which can be traced to Karl Mannheim's theory. WitrynaThe Westermarck effect, also known as reverse sexual imprinting, is a psychological hypothesis that states that people tend not to be attracted to peers with whom … When a locus is identified as imprinted, two different classes express different alleles. 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. Nucleus … Zobacz więcej Imprinting may cause problems in cloning, with clones having DNA that is not methylated in the correct positions. It is possible that … Zobacz więcej A similar imprinting phenomenon has also been described in flowering plants (angiosperms). During fertilization of the egg cell, a … Zobacz więcej In diploid organisms (like humans), the somatic cells possess two copies of the genome, one inherited from the father and one from the mother. Each autosomal gene is therefore represented by two copies, or alleles, with one copy inherited from each parent at Zobacz więcej Unfortunately, the relationship between the phenotype and genotype of imprinted genes is solely conceptual. The idea is frameworked using two alleles on a single locus and … Zobacz więcej In insects, imprinting affects entire chromosomes.
