T-007是一条雄性不育(MR)第二染色体,当与许多实验室标记染色体杂合时,它会引起传递比畸变(自费)。对T-007染色体的发育消除时间进行了研究。大约21%的T-007染色体预计将恢复的后代中的异源T-007男性丢失在受精和羽化之间的某个点(占29%的总畸变观察到的年轻男性)。T-007染色体数目的另52%在精子发生过程中由于精子细胞败育而丢失(占总畸变的71%)。T-007雄性在精子发生的最早期,每束精子细胞数和精子细胞尾部结构均出现异常。
T-007is a Male Recombination (MR) second chromosome that induces transmission ratio distortion (at its own expense) when heterozygous with many laboratory marker chromosomes. The developmental timing of elimination ofT-007chromosomes has been investigated. About 21% of theT-007chromosomes expected to be recovered among the progeny of heterozygousT-007males are lost at some point between fertilization and eclosion (representing 29% of the total distortion observed in young males). Another 52% of the expected number ofT-007chromosomes are lost as a result of spermatid abortion during spermiogenesis (representing 71% of the total distortion). Abnormalities in both the number of spermatids per bundle and the structure of spermatid tails are seen at the earliest stages of spermiogenesis inT-007males.
