Abstract excerpt
Male rats that were flown on Cosmos-1514 during their prenatal days 13 through 18 were investigated. The animals were sacrificed when they reached sexual maturity. Preparations were made of their testes for cytogenetic analysis: spermatocytes were at the stages of diakinesis--metaphase 1. The flown rats had 0.9% reciprocal translocations while the ground-based synchronous controls showed 0.5%. Exposure to space...
