Abstract

Chromosome configurations and also chiasma frequency throughout the metaphase I stage of spermatogenesis in the male horse are characterized in this work. The genome-wide frequency and distribution the chiasmata was detected together 49.45 ± 2.07 for 14 abundant stallions. All X and also Y chromosomes mutual a single chiasma at their pseudoautosomal region, while 1-4 chiasmata were observed in autosomal chromosomes. The chiasma frequency and also distribution were further studied because that 8 various bivalents identified by FISH in 5 fertile stallions. Hereditary length was calculated from chiasmata data for the totality genome and also for this 8 chromosomes. The findings complement the hereditary linkage data and provide insight into the genetic basis the spermatogenesis in normal stallions.
