Summary
| Description |
English: In the sperm of aged mice, as in older humans, we have found the largest age-related increases in two aneuploid conditions, XX8 and YY8. These curves show that the frequencies of aneuploid chromosomes in the sperm of mice increase with increasing age, especially after two years. This figure includes only those instances in which cells have gained a chromosome (X. Lowe, et al., "Aneuploidies and Micronuclei in the Germ Cells of Male Mice of Advanced Age", Mutation Research ; 1995)

Ce chiffre ne comprend que les cas dans lesquels les cellules ont acquis un chromosome
