Discovery of Supernumerary B Chromosomes in Drosophila melanogaster
B chromosomes are small, heterochromatic chromosomes that are transmitted in a non-Mendelian manner. We have identified a stock of Drosophila melanogaster that recently (within the last decade) acquired an average of 10 B chromosomes per fly. These B chromosomes are transmitted by both males and females and can be maintained for multiple generations in a wild-type genetic background despite the...
متن کاملChromosome elimination in maize induced by supernumerary B chromosomes.
The regular chromosomal complement of maize consists of 20 chromosomes. These are known as the A set and are invariably present in this number in all normal diploid plants. Heteropycnotic regions known as "knobs" are found in characteristic positions on the different A chromosomes, although the number of knobs varies greatly in different strains. Knobless races are known, while others have as m...
متن کاملSupernumerary chromosomes in mosaic Turner syndrome.
The finding of a supernumerary or marker chromosome in a karyotype poses difficulty in genetic counselling. The true incidence and significance of this chromosomal aberration is unknown in Malaysia. We report two patients who presented with supernumerary chromosomes in mosaic Turner syndrome.
متن کاملMultiple supernumerary chromosomes in the pseudogamous parthenogenetic
Polycelis nigrcl is a free-living simultaneous hermaphroditic flatworm that has amphimictic and pseudogamous parthenogenetic biotypes. Sexual individuals are always diploid (2n = 16) and pseudogamous parthenogens are polyploid (usually triploid). Two types of supernumerary chromosomes are found in parthenogens, those resembling autosomes ("A-like") and typical B chromosomes, both of which reach...
متن کاملSmall supernumerary marker chromosomes (sSMC) in humans.
Small supernumerary marker chromosomes (sSMC), defined as additional centric chromosome fragments too small to be identified or characterized unambiguously by banding cytogenetics alone, are present in 0.043% of newborn children. Several attempts have been made to correlate certain sSMC with a specific clinical picture, resulting in the description of several syndromes such as the i(18p)-, der(...
