Movie - Parental genomes

<Flowplayer height="325" width="320" autoplay="true">Parental_genome_mix_02.flv</Flowplayer>

Movie shows initial parental genomes mixing in early embryonic mitosis. In the mouse zygote, separation of chromatin according to parental origin is preserved up to the four-cell embryo stage and then gradually disappears. This movie shows that up to the 4 cell stage in the preimplantation embryo, the distribution of the 2 parental genomes remain segregated. After this stage, there is a gradual mixing of the 2 genomes with each cell division. Male Sperm Genome - light green Female Egg Genome - dark blue Image frames kindly provided by Thomas Haaf.
