What is the life expectancy of a parent deciding the life of a child?

A new study shows that the lifespan of the offspring is greatly influenced by the genes from the mother, after experiments on mice and expanding on human DNA.

The Science and Technology Daily reported that German and Swedish scientists have discovered some genetic variants in mitochondria that may affect later life, while the mitochondrial genome belongs to di transmission pattern system.

The study was carried out by a team of experts from the Max Planck Institute (Germany) and Karolinska Institute (Sweden). Through animal experiments, scientists found that when causing certain gene mutations in mitochondrial DNA in female mice, their offspring have an average life span of about 45 weeks, less than 10. weeks compared to normal ones.

In addition, mice with genetic defects also showed brain damage, motor dysfunction and other aging accelerating symptoms. Researchers explain: Mitochondria are the cell's "power plant", which provides shelter and energy for cellular activities.Mitochondrial damage is closely related to aging. Mitochondria have genetic material independent of the nucleus of the cell, only obtained through genetics from the mother. Scientists are extending this problem to human DNA.
