Q:

What does "genotype" mean?

A:

The meaning of "genotype" is the internal genetic makeup of an organism or cell. The genetic makeup of an organism determines its physical characteristics and predicts the physical characteristics of its progeny.

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.

  • Q:

    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.

    How do transient microbiota differ from normal microbiota?

    A:

    Normal microbiota, or normal flora, are bacteria that live in or on an organism all the time, while transient microbiota are not always present in the organism. Transient microbiota are a subset of normal microbiota.

    What describes an organism that exists as a group of cells?

    A:

    Earthlife states that an organism that is composed of groups of cells that work together is called multicellular. All living things consist of one or more cells, and almost any living thing visible without a microscope is a multicellular being. There are three kingdoms of multicellular organisms: plants, animals and fungi.

    What is an extended phenotype?

    A:

    The idea of an extended phenotype refers to the expression of genes in the behavior of an organism rather than its physical composition. The way a beaver makes a dam is influenced by the genetic makeup of the beaver, even though none of its genes code for dam making.
