DescriptionMouse sperm mutation fr2.jpg |
English: In the sperm of aged mice, as in older humans, scientist 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 (From X. Lowe, et al., "Aneuploidies and Micronuclei in the Germ Cells of Male Mice of Advanced Age", Mutation Research ; 1995)
Français : Chez la souris, comme chez l'humain, le taux de mutation des spermatozoïdes augmente. Il augmente le plus avec l'âge pour les mutations aneuploïdes, XX8 et YY8. Ces graphes montrent que les fréquences de chromosomes aneuploïdes dans le sperme de souris augmentent avec l'âge, surtout après deux ans. Ces chiffres ne concernent que les cas où les cellules (spermatozoïdes) ont acquis un chromosome supplémentaire (X. Lowe, et al., "Aneuploidies and Micronuclei in the Germ Cells of Male Mice of Advanced Age", Mutation Research ; 1995)
