Balanced Chromosomal Translocations of Parents in Relation to Spontaneous Abortions
The most significant complication of pregnancy is recurrent miscarriage. Numerous factors have been described as associations with recurrent wastage such as: uterine abnormalities, immunological factors, endocrinologic imbalance and chromosomal defects. Cytogenetic evaluation of couples with recurrent pregnancy losses is performed on the basis of G-banding technique only after other possible et...
متن کاملQuality Parametres of Emmer Wheat Landraces
Emmer wheat, Triticum dicoccum SCHUEBL, is an old variety of cereals which has been traditionally grown in aride areas. Nowdays, it is mainly grown in Italy, Spain, Turkey, Austria and in the Czech republic. This article deals with a study of quality parametres and selected economic parametres of 6 varieties coming from the genetic resources of emmer wheat. High crude protein content in grain w...
متن کاملMeiosis in two human reciprocal translocations.
Analysis of meiotic chromosomes from two human male translocation heterozygotes is reported. One had total sterility after maturation arrest and chain configurations at meiosis, and the second had a abnormal children who were presumed to be genetically unbalanced.
متن کاملReciprocal translocations in cattle: frequency estimation.
Chromosomal anomalies, like Robertsonian and reciprocal translocations, represent a big problem in cattle breeding as their presence induces, in the carrier subjects, a well-documented fertility reduction. In cattle, reciprocal translocations (RCPs, a chromosome abnormality caused by an exchange of material between non-homologous chromosomes) are considered rare as to date only 19 reciprocal tr...
متن کاملAneuploid analyses of three chlorophyll abnormalities in Emmer wheat.
Of the various chlorophyll abnormalities that occur in polyploid wheats, genetic bases of only two types, chlorina and virescence, are known. Here, for the first time, the chromosomal bases of three other chlorophyll abnormalities, striato-virescence, delayed virescence, and albino, which occur in Emmer wheat (2n = 4x = 28, genome constitution AABB) are reported. A set of disomic substitution l...
