Humans, for instance, have 46 chromosomes in a typical body cell, while dogs have 78. Of the 23 pairs of chromosomes, the first 22 pairs are called "autosomes." The final pair is called the "sex chromosomes." Sex chromosomes determine an individual's sex: females have two X chromosomes (XX), and males have an X and a Y chromosome (XY). It is consumed in large quantities. Wiki User 2014-06-10 21:26:10 This answer is: Study guides Genetics 17. Planter inneholder. These cookies will be stored in your browser only with your consent. Other names for this species: Fraises des Bois, Wild (European) Strawberry, European Strawberry, Woodland Strawberry, and Alpine Strawberry (the latter is the most common type in cultivation, which usually is nearly always everbearing, and produces few runners). These findings are of great interest, as few resistance genes have been characterized in strawberry, and they may represent new tools for molecular marker development that will allow breeders to coalesce multiple resistance genes into a single genetic background.
