Offspring sex ratio in the captive population of the Siberian crane (Grus leucogeranus Pallas)

Offspring sex ratio in the captive population of the Siberian crane (Grus leucogeranus Pallas) The sex ratio of Siberian crane chicks (Grus leucogeranus Pallas) from the captive population of the Oka Crane Breeding Center was analyzed with the use of molecular sex marker EE0.6 in 2009–2014. We determined the sex of 84 birds bred from 12 dams by means of artificial insemination and natural breeding. The total primary sex ratio was 40: 44, and the secondary sex ratio was 36: 39 with a minor female bias. The mortality rate of embryos was the same for both sexes. The primary and secondary sex ratio for the first eggs in clutches were in-line with total sex ratio. The relatedness of parents by microsatellite loci has no effect on sex ratio in chicks of naturally and artificially propagating dams. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The sex ratio of Siberian crane chicks (Grus leucogeranus Pallas) from the captive population of the Oka Crane Breeding Center was analyzed with the use of molecular sex marker EE0.6 in 2009–2014. We determined the sex of 84 birds bred from 12 dams by means of artificial insemination and natural breeding. The total primary sex ratio was 40: 44, and the secondary sex ratio was 36: 39 with a minor female bias. The mortality rate of embryos was the same for both sexes. The primary and secondary sex ratio for the first eggs in clutches were in-line with total sex ratio. The relatedness of parents by microsatellite loci has no effect on sex ratio in chicks of naturally and artificially propagating dams.
