Mosaicism or genetic mosaicism is a condition in which a multicellular organism possesses more than one genetic line as the result of genetic mutation. This means that various genetic lines resulted from a single fertilized egg. Mosaicism is one of several possible causes of chimerism, wherein a single … Zobraziť viac In 1929, Alfred Sturtevant studied mosaicism in Drosophila, a genus of fruit fly. Muller in 1930 demonstrated that mosaicism in Drosophila is always associated with chromosomal rearrangements and … Zobraziť viac Genetic mosaics are a particularly powerful tool when used in the commonly studied fruit fly, where specially selected strains frequently lose an X or a Y chromosome in one of the first embryonic cell divisions. These mosaics can then be used to analyze … Zobraziť viac • Zimmer, Carl (21 May 2024). "Every Cell in Your Body Has the Same DNA. Except It Doesn't". The New York Times.

WebFigure 3 Phenotypic mosaicism in PNH. (A) A hypothetical flow cytometry histogram of normal erythrocytes stained with FITC-labeled anti-CD59 (blue line). The dotted line represents staining with an irrelevant isotype control, and the vertical dashed line indicates lower limit of positive staining. Normal erythrocytes show bright, uniform staining. WebThis is called a mosaic karyotype because, like tiles in mosaic floors or walls, there is more than one type of cell. It is a fairly rare chromosomal disorder at birth, with an estimated incidence rate of about 1 in 15,000 live births.
