The objective of this study was to identify the quantitative trait loci (QTL) affecting carcass traits on chromosome 1 in Japanese quail. The populations comprised of 422 progeny in 9 half-sib families. Phenotypic data on carcass weight, carcass parts, and the internal organs were collected on 422 progeny. Nine half-sib families were genotyped for 8 microsatellite markers covering chromosomes 1...

in order to evaluate salt (nacl) tolerance in alfalfa (medicago sativa l.) half-sib families, a factorial experiment on the basis of completely randomized design, with 20-25 individuals in pot (replicates) was carried out under field conditions at the research station of university of tabriz. electrophoretic analyses were performed by using 7.5% slab polyacrylamide gels. two antioxidant enzymes...

HLA and Gm typing were carried out in 16 families. Seven families included 10 sib pairs with rheumatoid arthritis (RA) and autoimmune thyroid disease (ATD) respectively, and nine families included 16 sib pairs with RA and circulating thyroid autoantibodies respectively. Eight, 11, and seven sib pairs with either RA or clinical or immunological evidence of ATD shared none, one, and two HLA haplo...

Simulation was used to evaluate the performance of different selective genotyping strategies when using linkage disequilibrium across large half-sib families to position a QTL within a previously defined genomic region. Strategies examined included standard selective genotyping and different approaches of discordant and concordant sib selection applied to arbitrary or selected families. Strateg...

OBJECTIVE Given the familial influences on schizophrenia, it may be hypothesized that specific symptom domains also cluster within families, and that this applies to both clinical and subclinical levels of expression. This hypothesis was put to the test in a group of patients with a DSM-IV diagnosis of psychotic disorder together with their unaffected siblings, and a group of healthy sib-pairs....

After 50 days of pond culture fewer pike fingerlings (20 to 33 p. 100) were recovered from the mixing of two full-sib families than from isolated families. Growth and survival were influenced by the family effect. Environmental parameters, such as depth and extent of the banks, may also affect growth and survival. Our results indicated that isolating full-sib families and using small, shallow p...
