Scientists at Cambridge have unveiled a fascinating mechanism where fetuses use a paternal gene to control the mother's ...

X inactivation turns off entire chromosomes, whereas imprinting turns off only specific genes. How do these processes work, and why do they often produce similar results? Upon examining their ...

Researchers probe how gene imprinting affects the development of distinct species. By crossing two mouse species that normally do not interbreed, Howard Hughes Medical Institute (HHMI) researchers ...

Imprinted genes comprise a small subset of the genome whose epigenetic reprogramming in the germ line is necessary for subsequent normal embryonic development. This reprogramming and resetting of ...

Some of our genes can be expressed or silenced depending on whether we inherited them from our mother or our father. The ...

What is genomic imprinting? Created with Sketch. Genomic imprinting is the biological mechanism wherein genes are expressed differently depending on whether they are inherited from the mother or ...

What is the imprinted brain theory? Created with Sketch. Imprinted genes refer to genes expressed from one parent rather than from both. According to the imprinted brain theory, paternal gene ...

For example, DNA methylation modifies gene expression without altering the nucleotide sequence. A well-studied DNA methylation-based phenomenon is genomic imprinting (ie, genotype-independent ...

Can a kind of genetic favoritism explain why some people carry disease-causing mutations, but do not have a disease? | Genetics And Genomics ...
