...imation of heterosis and inbreeding depression are prerequisites to start hybrid development program. In this context, we explored heterosis and inbreeding depression in indigenous maize germplasm comprising inbred lines NCMLQ1, NCMLQ2, NCMLD1, NCMLD2, NCMLD3, and NCMLD4. ese genotypes were crossed to get ten F1 hybrid combinations, which were used...

...ence. The Fis inbreeding coefficients being negative in the sample populations for CAST loci imply heterogeneity in CAST loci (P<0.001). The effective allele number and allele density are other criteria to show the spatial heterogeneity in a population. The average effective allele number (ne) per loci for TGC samples from the smallholders in the villages, TGC ex-situ conservation herd and the total population sample were calcul...

...d a genetic isolation or inbreeding. We assessed the level of genetic diversity and genetic isolation of different langur populations using Randomly Amplified Polymorphic DNA (RAPD) genetic markers. We collected 86 different samples (feces 64, hair 13, blood 5, tissues 4) from 5 geographic langur populations of Pakistan and Azad Jammu and Kashmir (AJK) and succeeded in extraction of DNA from 23 samples, which were used for further genetic analysis. RAPD makers...

Highly significant inbreeding depression was recorded for all traits indicating a dominant type of gene action. Heterosis was high for both crosses along with high inbreeding depression. All these results exhibit that the hybrid breeding is the best option for inbreds to exploi...

In this study, four wild specimens groups (ZSW, WZW, NNW, and FZW) and four cultured specimens groups (ZSC, WZC, NDC, and FZC) of M. unguiculatus were used to analyze their genetic diversity, population structure and understand the relationship between the wild and cultured specimens groups. The results showed that haplotype diversity (h) of the cultured specimens groups (from 0...

Secondly, to examine the traditional maternal based strain classification system “Al Khamsa” using samples of native Arabian horses reared in the El-Zahraa stud based on 16 microsatellite markers. El-Zahraa stud showed high inbreeding (FIS = 0.110) and should be corrected by modifying mating system through avoiding excessive use of ...

...einberg equilibrium. The inbreeding coefficient in the three populations was quite high with a positive Fis value ranging from 0.000 – 0.422. Meanwhile, the value of the genetic differentiation index (Fst) in all populations is zero (0), indicating that there is no differentiation between breeds at the observed loci.

The total population of KBC in Nagari Batu Bajanjang, Tigo Lurah District is 1960, with an actual population of 610 chickens, an effective population of 600 chickens, and an inbreeding rate of 0.08%. The result showed the farmer’s profile 89.47% of respondents was in 25-55 years old, 47.37% respondent was eduucated in elementary school, 42.11% respondents has 5-10 years farming...

These measurements underlined the absence of inbreeding in the flocks that commonly causes inbreeding depression. The presence of genetic diversity was apparent and these marker...

...could reduce the risk of inbreeding due to loss of heterozygosity. Thus, we recommend the hybrid strategy of S. superciliaris ♀ × S. reevesae ♂ as the potential germplasm resources for further artificial reproduction. Population structure analysis and UPGMA tree indicated S. superciliaris and S. superciliaris ♀ × S. reevesae ♂ were clustered together that comprised of clade I, and S. reevesae and S. superciliaris ♂ × S. reevesae ♀...

A loss of genetic diversity was detected in the 2019 stock and significant differences were observed for number of different alleles, number of effective alleles, allelic richness and unbiased expected heterozygosity in the 2019 stock (P < 0.05). The highest pairwise relatedness and the lowest observed heterozygosity were also observed in 2019 stock. Moreo...

The UPGMA dendrogram based on Nei’s genetic distance revealed that the C. marulius population was divided into two major clusters. This study would be helpful to underpin the causes of decline in genetic diversity of C. marulius and provide significan...
