Genome Sequencing Reveals Scientists Overestimate Parental Gene Transfer

RedTracker| Researchers sequencing the entire genome of a family have refined the estimate of how many genes parents pass on to their offspring. Scientists have long estimated that each parent passes 75 gene mutations to their children.

Lynn B. Jorde, Ph.D., professor and chair of the Department of Human Genetics at the University of Utah School of Medicine. “The mutation rate was less than half of what we’d thought.”

By comparing the parents’ DNA sequences to those of their children, the researchers estimated with a high degree of certainty that each parent passes 30 mutations — for a total of 60 — to their offspring. via Science Daily
