How long a dog flea survives depends on several factors. The average flea survives a few days to two weeks without a food supply, and they can live much longer with a host.
Genotype, the genetic constitution of an organism. The genotype determines the hereditary potentials and limitations of an individual from embryonic formation through adulthood. Among organisms that reproduce sexually, an individualâs genotype comprises the entire complex of genes inherited from both parents.
Genotypic and genomic sequence. The genotype of an organism is the inherited map it carries within its genetic code. Not all organisms with the same genotype look or act the same way because appearance and behavior are modified by environmental and developmental conditions. Likewise, not all organisms that look alike necessarily have the same genotype. One's genotype differs subtly from one's genomic sequence.
