The sum total of all observable features of an organism is?
Answer Details
The sum total of all observable features of an organism is called the phenotype. The phenotype includes physical traits, such as height, eye color, and hair texture, as well as behavioral traits, such as a person's ability to run quickly or play a musical instrument. The phenotype is influenced by both genetic and environmental factors. The genetic component of the phenotype is determined by the organism's genotype, which is the complete set of genetic information that it carries, while the environmental component is determined by the conditions in which the organism lives, such as the availability of food and water, the temperature, and the presence of other organisms.
Heterozygous and homozygous are terms that describe the relationship between two copies of a gene in an organism's genotype. Heterozygous means that the two copies of the gene are different, while homozygous means that the two copies are the same. These terms are used to describe the genetic makeup of organisms and can be used to predict the likelihood of certain traits being expressed in the phenotype.
