The author explains that there is no single definition of species and then describes the biological species concept, which depends on reproductive compatibility. This approach has several problems, however, and the author goes on to say that phenotype may be used when the biological species concept...

Most cases are associated with dominantly inherited mutations or deletions of the PAX6 gene. This article will review the clinical manifestations, the molecular basis including genotype–phenotype correlations, diagnostic approaches and management of aniridia. In brief Aniridia is a rare, sight-...
This example describes the construction of an adenovirus based vector which expresses MAGE-3, and the infection of monocyte derived, dendritic cells thereby. The recombinant adenovirus, referred to as “Adeno.MAGE-3,” was generated via in vivo homologous recombination in 293-EBNA cells, described ...
