Q:

What is the genetic makeup of an organism called?

A:

Quick Answer

The genetic makeup of an organism is known as its genotype. The genotype refers to the set of traits found within the cells of living organisms. These traits, known as the genetic code, are passed from one generation to the another during cell division and reproduction.

Full Answer

The genetic code of an organism is stored in strands of DNA molecules, contained as linear sequences consisting of adenine, guanine, cytosine and thymine. Each of these nitrogenous bases, represented by the letters A, G, C and T, are arranged in sequences of three-letter codes, referred to as triplets or codons. There are 64 combinations of three-letter codes of these bases.

    What is genetic manipulation?

    A:

    Genetic manipulation, also called genetic engineering, refers to the alteration of the genes of an organism. It involves manually adding new DNA to an organism to add new traits. Examples of genetically engineered organisms include plants that are resistant to certain insects, plants that tolerate herbicides and crops with altered oil content.

  • 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.

  • Q:

    What is genetic diversity?

    A:

    Genetic diversity accounts for the difference in genes among individuals and species. Genetic diversity, or genetic variation, gives living organisms unique traits that distinguish them from even their closest relatives. Genetic variation explains differences in human facial features, breeds of dogs and cats, height and size of plants and many more alterations.
