what is a phenotype.?

Question

Please givephenotype in a defanition

Answer 1

The phenotype is the outward expression (physical characteristics) of the genotype (allelic makeup of DNA).

Answer 2

"The phenotype of an individual organism is either its total physical appearance and constitution or a specific manifestation of a trait, such as size, eye color, or behavior that varies between individuals. Phenotype is determined to a large extent by genotype, or by the identity of the alleles that an individual carries at one or more positions on the chromosomes. Many phenotypes are determined by multiple genes and influenced by environmental factors. Thus, the identity of one or a few known alleles does not always enable prediction of the phenotype."

Answer 3

phenotype are characterstics which vary between people of different regions. jewish people have large noses. while asains have small ones. those are different phenotypes. skin,eyes,nose,hair its all relavent



phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). To consider these in the context of evolutionary biology, we want to know how these two are related. In a narrow "genetic" sense, the genotype defines the phenotype. But how, in and evolutionary sense, does the phenotype "determine" the genotype? Selection acts on phenotypes because differential reproduction and survivorship depend on phenotype. If the phenotype affecting reproduction or survivorship is genetically based, then selection can winnow out genotypes indirectly by winnowing out phenotypes.

Answer 4

Genotype and phenotype are related definitions;
Genotype is the actual DNA in the organism, phenotype is the way that gene is expressed in the organism.

For example, a combination of pigment alleles on your chromosome is your genotype. The color of your hair is your phenotype.

Answer 5

it is the physical attributes of an organism. For example the molecules, macromolecules, cells, structures, sum of the atoms, tissues, organs, reflexes and their behaviors. it also is the function or behavior of a living organism

Answer 6

Its someones physical appearance or trait.
