| description | <p>Having higher adaptability against abiotic stress, which
is characterized in rural areas in developing countries, local farm animal
genetic resources (FAGRs) are increasingly precarious for random and
unsystematic crossing with exotic breeds. In this study, 85
microsatellite loci were utilized to assess genetic diversity among native
Algerian rabbits (NARs) sampled from an area of 753 km (from north
to south) and 919 km (from east to west). Those distances covered
25 significant geographical points in seven rural areas (El Taref, Mostaganem,
Sidi Bel Abbès, M'Sila, Dar Chioukh, Faidh El Botma, and Laghouat). A
total of 558 alleles were observed in this study. The highest genetic
diversity was registered in the southern direction among NAR populations. The
mean number of alleles per locus (MNa) and the inbreeding coefficient (<span class="inline-formula"><i>F</i><sub>IS</sub></span>)
were highest in Laghouat (4.482 and 0.232), while they were lowest in El Taref
(4.000 and 0.149). In the current study, the number of private alleles (Pa)
ranged from 9 to 23. In addition, the average of observed heterozygosity
(0.427) was lower than the expected value (0.524) due to high levels of
inbreeding. The discriminant analysis of principal components
(DAPC), the neighbor-joining tree (NJ), and the analysis of STRUCTURE software confirmed the
classification of populations according to geographical zones into four
main groups (east, west, south, and middle). The results of the current
study are useful for breeding improvement and conservation plan research in relation to
local animal genetic resources in Algeria.</p> |
