Chromosomal Studies

Oct 30, 2016. The laboratory specialist uses a microscope to examine the size, shape, and number of chromosomes in the cell sample. The stained sample is photographed to show the arrangement of the chromosomes. This is called a karyotype. Certain problems can be identified through the number or arrangement of.

While parents who carry chromosomal rearrangements are at increased risk to have further miscarriages or babies born with health problems, they can also produce healthy children. Chromosome studies can be performed on parents' blood to see if either parent is a carrier of a chromosomal rearrangement. Gene Mutation:

However, no cytogenetic information is available for both Hepsetidae and Alestidae species, thus preventing any evolutionary comparative studies at the chromosomal level. In the present study, we are providing new cytogenetic data for Hepsetus odoe, including the standard karyotype, C-banding, repetitive DNAs.

Jun 30, 2017. Recent molecular approaches such as chromosomal microarray-based analysis ( CMA) use DNA isolated from CV or fetal tissue samples. Its success rate has been reported to be slightly higher than that expected for cytogenetic analysis, since it does not require cell culture. CMA has a much higher ability.

Jun 16, 2017. Genetics can provide invaluable information on the ancestry of the current inhabitants of Cyprus. A Y-chromosome analysis was performed to (i) determine paternal ancestry among the Greek Cypriot (GCy) community in the context of the Central and Eastern Mediterranean and the Near East; and (ii).

Oct 13, 2017. For the majority of Rhinolophus species a karyotype consisting of either 58 or 62 chromosomes was reported. The members of the R. trifoliatus clade are therefore distinguished from other rhinolophids by low diploid chromosome numbers (2n) and a high rate of chromosomal changes. Recently, based on.
