The hormonal mayhem, reduced fertility and hot flushes experienced by a woman in the run up to menopause may owe to warfare between her own genes, according to a team of scientists working in the United Kingdom and Japan.
University of Warwick scientists have discovered a "nourishing gene" which controls the transfer of nutrients from plant to seed - a significant step which could help increase global food production.
In flowering plants, the beginning of embryogenesis is almost exclusively governed by maternal gene activity. Maternal factors regulate the development of the embryo and silence paternal genes during early stages of development. ...
Mom's influence comes first: Maternal genes dominate in developing brains, while paternal ones lead in adult-hood
(PhysOrg.com) -- Genome-wide analysis of mice brains has found that maternally inherited genes are expressed preferentially in the developing brain, while the pattern shifts decisively in favor of paternal influence by adulthood.
(PhysOrg.com) -- An analysis of rare genetic disorders in which children lack some genes from one parent suggests that maternal and paternal genes engage in a subtle tug-of-war well into childhood, and possibly as late as ...
A new study reveals that - contrary to decades of evolutionary thought - chromosome regions that are prone to breakage when new species are formed are a rich source of genetic variation.
