5. Prediction of breeding values and selection responses with genetic heterogeneity of environmental variance.

There is empirical evidence that genotypes differ not only in mean, but also in environmental variance of the traits they affect. Genetic heterogeneity of environmental variance may indicate genetic differences in environmental sensitivity. The aim of this study was to develop a general framework...

6. Effect of chosen factors on growth of lambs crossbreeds with using Suffolk in sire position.

The aim of the study was evaluated the effect of chosen factors (sex, litter size, year of the study) on the growth of lambs crossbreeds with using Suffolk (Sf) in the sire position. In the mother position there were used following genotypes: Charollais (Ch), Sf 50 Ch, Improved Wallachian (IW) and...

8. The cytotoxicity and genotoxicity of hexavalent chromium in medaka (Oryzias latipes) cells.

Chromium is an increasing health concern for aquatic environments, however, the mechanism of chromium toxicity in aquatic species is yet unknown. We used a medaka (Oryzias latipes) fin cell line to investigate the cytotoxicity and genotoxicity of sodium chromate, a soluble form of hexavalent...

11. Analysis of polymorphisms in exon 14 in porcine Mx1 gene and identification of new mutation points.

By the PCR-RFLP method, the polymorphisms of exon 14 of Mx1 gene were detected in 7 native and foreign pig breeds. Taken together with the analysis of restriction enzyme Hin6 I digestion, there were 6 genotypes and 3 alleles. And, all individuals of Duroc exhibited the AA genotype but the Sutai...

13. Characterization of a spontaneous, pressure-tolerant Listeria monocytogenes Scott A ctsR deletion mutant.

A spontaneous, pressure-tolerant mutant of Listeria monocytogenes Scott A, designated 2-1, was isolated after several rounds of pressure treatments at 500 MPa for 10 min. Mutant 2-1 was almost 100 000-fold more resistant than the wild type to a pressure of 350 MPa, and about 100-fold more resistant ...

17. cDNAs cloning of growth hormone, growth hormone receptor and the different expression between male and female Nile tilapia Oreochromis niloticus.

In order to study sex differences in growth in the Nile tilapia (Oreochromis niloticus), we cloned the cDANs encoding growth hormone and growth hormone receptor from pituitary or liver RNA by Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and compared their expressions between male and...

18. Effect of crossbreeding between two strains of Red Tilapia (Oreochromis spp.) on the mortality and larval production at 30 days.

The most important fish species cultured in Colombia is the Red Tilapia (Oreochromis spp.), hybrid conformed by the cross of four species of the genus. Its productive performance can be jeopardized by effects of consanguinity and the use of deficient strains or combinations. This research tested...

19. Genetic Management of Aquaculture Stocks in Sub-saharan Africa. Report of a Producers' Workshop Accra, Ghana, 27 February - 3 March 2006.

Aquaculture producers compete in a global market. While to date Africa's market share has been nearly inconsequential, there is rapidly expanding investment in aquaculture in Africa and the real potential that the region could become an important aqua-producer. However, while investment is growing...
