Maulana Naji, Cord Drögemüller, Gábor Mészáros, Johann Sölkner
Acta Univ. Agric. Silvic. Mendelianae Brun. 2019, 67(5), 1183-1188 | DOI: 10.11118/actaun201967051183
Confirmed by phenotypic records, several studies across different breeds in different locations have linked missing homozygous pattern with several defects in the functional system and recessive genetic disorders. Recessive genetic diseases are expressed when the recessive alleles appear in a homozygous state for an individual. One of the indicators to detect the recessive allele is through haplotypes, which have a normal frequency in the population, but never occur in the homozygous state. In this study, we used SNP genotypes of 220 Austrian Tyrol Grey cattle and 80 Italian Tyrol Grey cattle to identify the haplotype blocks (Hapblocks) that possibly...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2019, 67(5), 1379-1392 | DOI: 10.11118/actaun201967051379
Intra-ECOWAS trade and food evxports have been debated and given attention in recent years. The paper uses an analytical tool, called 'products mapping' following some methods, such as trade balance index, Balassa index and Lafay index to analyse comparative advantages in all 46 food items (SITC 0 + 1 + 22 + 4) in trade between Nigeria and ECOWAS as well as the world. The findings suggest that Nigeria has performed better in trading with other ECOWAS countries than in trading with the overall world market. For Nigeria and the world, the findings reveal that the country's comparative advantages reduced from 12 out of 46 (12/46) in 1995 to 8/46 food...
