English: Early cleavages and timing of gastrulation are unaffected in cybrid embryos. Animal view of the diverse kinds of X. laevis egg-based embryos reveals that haploid [ l ]x l (middle) and [ l ]x t cybrid (bottom) embryos cleave and begin gastrulation synchroneously, about 50 minutes after diploid l x l (top) embryos. A star was added to the right of embryos at the onset of gastrulation (stage 10), when embryo-wide cellular movements begin. Images were captured every 4 minutes at ∼26°C, and displayed at a rate of 10 images per second. (MOV)
