Genetics
... Mendel’s Law of Segregation states that for each trait (gene), each organism carries two factors (alleles), and that each of the organism’s gametes contains one and only one of these factors. In this way, the alleles segregate during meiosis, providing for genetic variability among the organism’s of ...

Human and murine PTX1/Ptx1 gene maps to the region for Treacher
... PTX1, like its murine and chick homologs, possesses a homeodomain with a bicoid-class third helix. The homeodomain is highly conserved between mouse and human (100%), as are the Cand N- termini (88 and 97% respectively; Fig. 3a,b). This conservation is also evident at the level of gene structure as ...
