The domestication of Emu (Dromaius novaehollandiae) began in the 1970s, but their productive characteristics have not undergone significant genetic enhancement. This study investigated the inbreeding and genetic diversity of 50 emus from various farms in Japan using Double digest restriction-site associated DNA sequencing (ddRAD-seq) markers. Single nucleotide polymorphism (SNP) calling revealed 1,71,975 high-quality SNPs while runs of homozygosity (ROH) analysis identified 1,843 homozygous segments, with an average of 36.

Yakutian cattle are adapted to Siberia's harsh sub-arctic conditions, enduring temperatures below -70°C. However, the population genetics studies on this breed are scanty, to document the genetic uniqueness in these cattle.

Using 85,001 high-confidence SNPs, the investigation into ROH distribution unveiled nuanced patterns of autozygosity across individuals especially in 2 out of the 8 farms, exhibiting elevated ROH levels and mean genome coverage under ROH segments. The prevalence of shorter ROH segments (0.

In animal breeding history, genetic admixture has provided both short-term and long-term advantages by utilizing the phenomenon of complementarity and heterosis in several traits and genetic diversity, respectively. The traditional method of admixture analysis by pedigree records has now been replaced greatly by genome-wide marker data that enables more precise estimations.

A series of six univariate animal models were employed to calculate estimates of (co)variance components and heritability for first lactation reproduction traits. Among these models, Model 2 was identified as the best fit for age at first calving (AFC) and calving interval (CI), while Model 1 proved optimal for service period (SP) and conception rate (CR).

Background: Autologous hair transplantation has been the convention in cases of androgenic alopecia. Routinely, the occipital area serves as an ideal donor site. The advent of follicular unit extraction (FUE) has made body and beard hair harvest a possibility.

Out of all the carcinomas affecting the lower lip, squamous cell carcinoma accounts for 95% of the patients. Reconstruction of lower lip is a challenging task, as it requires taking into consideration the restoration of function as well as aesthetics.
