in order to genetic analysis of rice seed vigour, a cross was carried out between tarom mahalli (tolerant to osmotic stress) and khazar (sensitive to osmotic stress) crosses. linkage map based on ssr markers was derived using 74 polymorphic markers and 192 f2 individuals. germination rate, radicale and plumule length were recorded from 20 plants per 192 f3 families. the loci related to germinat...
Recombinant lambda phage Charon 4A with repetitive human DNA inserts have been constructed by using cellular DNA from a human-Chinese hamster ovary cell hybrid retaining the complete hamster genome and a single human chromosome 12. One recombinant phage, 12-11, contains several repetitive sequences, each with a different repetition pattern in the human genome. A 2.2-kilobase (kb) EcoRI fragment...
CONTEXT The only genetic locus universally accepted to be important as a risk factor for late-onset Alzheimer disease (AD) is the apolipoprotein E (APOE) locus on chromosome 19. However, this locus does not account for all the risk in late-onset disease, and a recent report has suggested a second locus on chromosome 12p11-12. OBJECTIVE To look for evidence of linkage on chromosome 12 and to t...
The insertional mouse mutation Adp (Acrodysplasia) confers a parent-of-origin developmental phenotype, with animals inheriting the mutation from their father showing skeletal abnormalities, whereas those inheriting the mutation from their mother are normal. This parental-specific phenotype, along with mapping of the insertion to a region of chromosome 12 proposed to contain imprinted genes, sug...
BACKGROUND AND AIMS Inflammatory bowel disease (IBD) includes ulcerative colitis and Crohn's disease, both of which are multifactorial diseases involving the interaction of genetic and environmental factors. A region on chromosome 12 centred around the marker locus D12S83 has previously been associated with IBD predisposition. The aim of the study was to investigate this genetic region in an in...
A 39 year old male with primary infertility was diagnosed as having Klinefelter syndrome by conventional cytogenetic analysis, which also showed an abnormal chromosome 12. Fluorescence in situ hybridisation (FISH) analysis of the aberrant chromosome using a 12 specific centromeric probe showed a break in the alphoid repeats followed by an inversion within the short arm, resulting in a pseudodic...
A cDNA clone for human immune interferon (IFN-gamma) gene sequences, plasmid p69, was used to chromosomally map the IFN-gamma gene by detecting human IFN-gamma gene sequences in DNA isolated from human-rodent somatic cell hybrids. We were able to map the IFN-gamma gene by correlating the human chromosomes present in these hybrids with the human specific 8.8 and 2.0 kilobase pair fragments produ...
Previous studies have identified multiple blood pressure and renal disease quantitative trait loci located on rat chromosome 12. In the present study, we narrowed blood pressure loci using a series of overlapping Dahl salt-sensitive/Mcwi (SS)-12 Brown Norway (BN) congenic lines. We found that transferring 6.1 Mb of SS chromosome 12 (13.4-19.5 Mb) onto the consomic SS-12BN background significant...
