Some of the most common diseases are infections caused by bacteria, such as Campylobacter, Salmonella, Shigella, E. coli O157:H7, Listeria, botulism, and norovirus.
A genotype is the actual genetic coding for an organism. A phenotype is the physical appearance. For example, let's say BB or Bb is the coding for black hair. BB/Bb is the genotype, and the black hair is the phenotype.
The phenotype is what the genes make the characteristics look like. For example, if EE is for large eyes, and ee is for small eyes, you can determine the phenotypes from theâ¦se. If the genotype is EE or Ee, the person has large eyes. If the person is ee, then he or she has small eyes.
