“…This was consistent with the results reported by Grzegorczyk et al [ 33 ]. Haplotype (Hd) and nucleotide (Pi) diversity are important indicators of the genetic diversity of a population [ 34 ]. Li et al determined the mtDNA D-loop sequences of 26 goose breeds and six Lande geese, among which the average Hd of the Chinese goose breeds was 0.1384 and the Pi was 0.00029 [ 35 ].…”

To explore the differences in body-weight traits of five goose breeds and analyze their genetic diversity and historical dynamics, we collected body-weight data statistics and used Sanger sequencing to determine the mitochondrial DNA of 100 samples of five typical goose breeds in China and abroad. The results indicated that Lion-Head, Hortobagy, and Yangzhou geese have great breeding potential for body weight. Thirteen polymorphic sites were detected in the corrected 505 bp sequence of the mitochondrial DNA (mtDNA) ND6 gene, accounting for approximately 2.57% of the total number of sites. The guanine-cytosine (GC) content (51.7%) of the whole sequence was higher than the adenine-thymine (AT) content (48.3%), showing a certain GC base preference. There were 11 haplotypes among the five breeds, including one shared haplotype. We analyzed the differences in the distribution of base mismatches among the five breeds and conducted Tajima’s D and Fu’s Fs neutral tests on the historical dynamics of the populations. The distribution of the mismatch difference presented an unsmooth single peak and the Tajima’s D value of the neutral test was negative (D < 0) and reached a significant level, which proves that the population of the three species had expanded; the Lion-Head goose population tends to be stable. The genetic diversity of Lion-Head, Zhedong White, Yangzhou, and Taihu geese was equal to the average diversity of Chinese goose breeds. The Hortobagy goose is a foreign breed with differences in mating line breeding and hybrid advantage utilization.

“…Camels are regarded as sustainable livestock genetic resources despite their reduced relevance as draft power in the current scenario. Resilience to climate change and high production efficiency of camels has ensured their survival in diverse ecosystems against the harsh reality of destruction of their habitats (Satyanarayana et al 2022). They constitute an important means of transport in the desert landscapes, in addition to being acknowledged for their unique ability to tolerate hostile conditions, unusual immune system and beneficial attributes of their milk (Ali et al 2019, Sharma et al 2020.…”

Recombination regulator, PRDM9, has been regarded as the most rapidly evolving gene in the genomes of many metazoans, in addition to being acknowledged as the sole speciation gene in vertebrates. It has become the focus of many scientific investigations because of exceptional numerical and sequence variability in its zinc finger (ZF) domain within and across species that contributes to reproductive isolation between species. This study is the maiden attempt to explore the architecture of PRDM9 ZF domain in two Camelid species (Camelus dromedarius and Camelus bactrianus). Sequence analysis revealed highly conserved domain architecture with presence of 3 and 4 ZFs in dromedary and Bactrian camels, respectively. Typical evolutionary features of PRDM9 ZF domain i.e. concerted evolution and positive selection were invariably absent in both the one-humped dromedary and the two-humped Bactrian camels. Fertility of hybrids of dromedary and Bactrian camels, despite being taxonomically distinct species can be attributed to the lack of sequence variability in PRDM9 in these species. Phylogenetic analysis underpinned clear demarcation of camels from other livestock species. The results of the present study defy what has been learnt so far about PRDM9 and add to the enigma surrounding the most intriguing gene in the genome.
