The mechanism behind this phenomenon, known as genomic imprinting, is determined by DNA modifications during egg and sperm ...

You're not an equal product of both parents' genes. Genomic imprinting, a process whereby only one gene copy is expressed, not only exists but, combined with mutations, may lead to disease.

Not only are alleles inherited from a mouse’s mom or dad expressed in unequal proportions in various cells in the brain and adrenal system—a phenomenon called genomic imprinting—but expressing the ...

In a groundbreaking study, scientists from China have successfully created mice with two biological fathers. Though the ...

Parthenogenesis, asexual reproduction, is precluded by the need for two separate genomes with individual imprinting, that is, the specific inactivation of genomic regions by epigenetic ...
