Poecilia formosa Transcriptome or Gene expression

Poecilia formosa stands out from all other aquatic models by the unique feature of genetic clonality. This is due to its unusual mode of reproduction. Females produce diploid eggs without meiosis, which are then triggered for parthenogenetic development by sperm of males from related species. There is, however, no paternal genetic contribution and all offspring develop as clones of their maternal lineage. The proven true clonality thus allows researchers to perform experiments with animals that are genetically identical. This guarantees the utmost reproducibility of independent studies, a stereotype development of diseases or physiological processes under scrutiny and a highly comparable biological material.
