Aging predisposes oocytes to meiotic nondisjunction when the cohesin subunit SMC1 is reduced.
In humans, meiotic chromosome segregation errors increase dramatically as women age, but the molecular defects responsible are largely unknown. Cohesion along the arms of meiotic sister chromatids provides an evolutionarily conserved mechanism to keep recombinant chromosomes associated until anaphas...
