The widespread use of mutagenesis for plant genetic improvement can be explained by a number factors, including the fact that new varieties developed in shorter time than conventional breeding methods and transgenesis is more difficult to re-engineer. Gamma rays are physical mutagens often used techniques safe human health because there no environmental risk induced generations. method this pap...
In India, Holstein and its crosses are being used extensively in breeding programmes and all these breeding bulls are screened for autosomal recessive genes. Blood samples are collected in ethylenediaminetetraacetic acid (EDTA) coated tubes and DNA was isolated by using phenol-chloroform method. Polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) wereperformed by using...
This is the first description of the polymorphisms of arylalkylamine-N-acetyltransferase (AA-NAT) gene in Indian goats with different reproductive traits (twinning percentage and age of sexual maturity). Based on the important role of AA-NAT in reproduction, it is considered as a possible candidate gene for this trait. Two novel synonymous SNPs, C825T (exon2) and C1249T (exon3) were identified....
A total of 423 blood samples were collected (during 2009 and 2010) from all the ram holdings at three major Jordanian governmental Awassi breeding stations (Al-Khanasry, Al-Mushairfa and Al-Fjaje) and two private flocks. All blood samples were screened for the presence of mutations at the CNGA3 gene (responsible for day blindness in Awassi sheep) using RFLP-PCR. The day blindness mutation was d...
Bone morphogenetic protein 15 (BMP15) is a member of the transforming growth factor beta superfamily, is specifically expressed in oocytes and is essential for sheep prolificacy. Reported mutations in this gene cause increased ovulation rate and infertility in a dosage-sensitive manner. In this work, a new naturally occurring mutation in the BMP15 gene from the ovine Rasa Aragonesa breed is des...
Bovine leukocyte adhesion deficiency (BLAD) is a genetically transmitted disease and inherited as an autosomal recessive defect. Keeping this in view the present study was conducted to estimate incidence of carrier animals in a herd of breeding bulls for mutation in Integrin â2 gene, reared at Frozen Semen Bull Station (FSBS), Haringhata, Nadia, West Bengal, India. A total of 80 bulls of differ...
