Summary

Story summary

University of Pennsylvania researchers report parent-of-origin effect on telomere length in mice.
Maternal short telomeres with paternal long telomeres elongate offspring telomeres; the reverse shortens them in mice.
The results indicate telomere length is not determined by genetic sequence, but by parental contribution.
Findings could inform aging and cancer research, as the study examines telomere behavior during early embryonic development.
