ABSTRACT
Asadi N, Esmaeelkhanian S., Cytogenetic analysis of bactrian-dromedary crossbreed camels. Onl J Vet Res., 20(9):602-606, 2016. Male Bactrian camels were crossbred with female dromedaries and cytogenetic markers in 15 of their male offspring are described. Chromosomes were divided according to position of centromere comprising acrocentric autosomes 1-31, metacentric autosomes 33 and 34 and 2 autosomal sub metacentric chromosomes 35 and 36 and a pair of sex chromosomes. X chromosome was large metacentric and Y chromosome small acrocentric. Mean length of longest chromosome was 12.2μm and shortest 2.5μm. The diploid chromosome number for hybrids was 74 chromosome with a karyotype of 32 acrocentric, 3 metacentric and 1 pair sub metacentric autosomes. The small arms of acrocentric chromosomes were C-band positive and interstitial C-bands were associated with the centromere of the sub metacentric chromosomes.
