Genetic Diversity in Growth Hormone Gene of Three Colour Type Populations of Camels in Yobe State
This research was conducted to investigate the genetic diversity of three camel colour type populations in Yobe State. A total of 100 camels of three distinct colour types (Grey White (GW), JA and Kurri (KR) from Yobe state were sampled for the study. Five samples from each of the populations were sequenced to examine molecular diversity parameters as well as the presence of single nucleotide polymorphism (SNPs). Generally, the result showed transition between the haplo-groups and the reference. Two SNPs (C→T transition) were observed at positions 062 and 232, respectively in the haplotypes. Highest genetic variability was observed in molecular indices among the GW color type. The analysis of molecular variance (AMOVA) revealed higher genetic variability within population than between populations. The neutrality test of population expansion revealed that the GW and KR were expanding while JA population was shrinking. The phylogenetic analysis showed that all the camel colour types shared same origin before divergence, with KR and JA being closer to each other than they were to GW.
