Full Answer

The term "genotype" is typically used in reference to a specific characteristic. Essentially, genotype refers to all of the genes that an organism carries, regardless of whether those genes are expressed. Organisms that reproduce sexually typically have two copies of a specific gene. In some cases, a gene can be recessive to another counterpart gene, which means that if the counterpart gene is present, it is expressed in lieu of the recessive gene. Therefore, it is possible for an organism to carry a recessive gene without expressing it, and although the gene is not physically apparent, it can be passed onto future progeny. The organism is said to have a recessive trait.

    What is the difference between genotype and phenotype?

    A:

    An organism's genotype is the entire set of genes that it carries in its genome, and its phenotype is the observable effect of those genes on the body and behavior of the organism. Biologists draw a distinction between genotypes and phenotypes to clarify the difference between an organism's genetic heritage and the effects that its combination of genes has.

    What are multicelled organisms?

    A:

    A multicelled, or multicellular, organism is any living being comprised of more than one cell. Typically, multicellular life differentiates cells into specialized tasks, which in larger organisms can form tissues and organs. This allows multicellular organisms to have cells that are more efficient at a specific function of life.

    What is an example of a heterotroph?

    A:

    A heterotroph is any organism, including carnivores, omnivores and herbivores, that cannot produce its own food through solar energy and must feed off another life form. In the food chain, heterotrophs represent the consumers. The autotrophs, such as plants and algae, are called the producers of the food chain because of their ability to produce their food with no need to consume another organism.

    What is a vector in biology?

    A:

    In biology, a vector is any organism that facilitates the spread of a disease. Vectors do not inherently cause diseases but are mere vehicles of the germs that cause disease. Vectors may include small insects or larger animals that carry viruses from one host to another.
