Embryo splitting or twinning has been widely used in veterinary medicine over 20 years to generate monozygotic twins with desirable genetic characteristics. The first human embryo splitting, reported in 1993, triggered fierce ethical debate on human embryo cloning. Since Dolly the sheep...
a) splitting of the blastocyst b) fertilization of more than one ova c) polyspermy d) inappropriate implantation of the embryo into the endometrium e) splitting of the morula while ells are still totipotent. Explain fertilization. Contrast the monozygotic and the dizygotic twins from fertilization...

If a group of cells or even one single cell is separated from the early embryo they (respectively it) can nevertheless “exercise their totipotentiality and produce a clone or twin” (Ashley &Moraczewski, 2001). So, the individuality-charge asks how an embryo can actually be an individual...
The major barriers for advancing research onEhrlichiasp. HF, however, have been the inability to stably culture it in a mammalian macrophage cell line and lack of genome sequence and analysis data. Previously, it was cultured in monkey endothelial RF/6A cells andIxodes scapularistick embryo ISE6...
This procedure randomly shifts the position of the modules along the cortex without splitting apart the components of the module (Figure S2) (Bethlehem et al., 2017). The resulting null distribution of community partitions preserves the number and size of modules, as well as the spatial ...
From five pairs of twin blastocysts, the fluorograms provided detectable STR profiles for identical peak position between the twin embryos. This is the first report on twinned human embryos to prove monozygocity at the DNA level. Embryo splitting exhibits novel potential for future applications in ...
