Imprint hypothesis
WitrynaBefore, I concluded that both the imprint hypothesis and the pulse hypothesis of generations play a part in the formation of generations. After reading through some of the sources I have picked out, I’ve instead concluded that the imprint hypothesis is the most logical explanation to the driving force behind generations.

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.
