Malus sieversii modern apple cultivars. Unlike domesticated varieties its leaves go red in autumn: 62.2% of the trees in the wild do this compared to only 2.8% of the regular apple plant or the 2,170 English cultivated varieties. The species is now considered vulnerable to extinction. "Malus sieversii" has previously been identified as the main contributor to the genome of the cultivated apple ("Malus pumila"), on the basis of morphological, molecular, and historical evidence. A DNA analysis in 2010 confirmed "M. sieversii" as the progenitor of the cultivated apple. A third species that has been thought to have made contributions to the
Genesee Scientific the world leader in innovation for and supply to the "Drosophila" (fruit fly) research community. "Drosophila" are widely used as a model organism in the field of genetics. Genesee Scientific has been awarded three patents by the United States Patent and Trademark Office for its revolutionary "Drosophila" vial racking system (patent numbers D673,296 S; 8,136,679 B2; and 8,430,251 B2). This "Drosophila" vial racking system significantly decreases time spent racking vials and is more environmentally friendly compared to traditional vial packaging configurations. Genesee Scientific has also developed the first atlas of "Drosophila" phenotypic markers available on mobile devices. Genesee the "Drosophila"
