leptotene การใช้

The chromomeres are present during leptotene phase of prophase I during meiosis.
In mice, leptotene, zygotene and early pachytene are enriched for FANC proteins.
When the PMCs are in leptotene-zygotene, very few tapetal nuclei are in endomitosis.
In the non-mutant mouse, FANCG protein is expressed in spermatogonia, preleptotene spermatocytes and spermatocytes in the leptotene, zygotene and early pachytene stages of meiosis.
Irradiation during the leptotene-zygotene stages of meiosis, that is, prior to the pachytene period in which crossover recombination occurs, was found to increase subsequent chiasma frequency.
