Imprinting

Not just humans benefit from animal biotechnology

... effective when one of the copies is already silenced, as happens in the phenomenon known as genomic imprinting. Sang cited the case of sheep, where imprinting of a gene called callipyge leads to increased muscle growth in the hindquarters, which clearly can be a desirable trait in meat production. All ...

New research explores newborn in-hospital weight loss

The most influential predictor of weight loss in newborns is the type of infant feeding, conclude the authors. ...
