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.
