what does the term phenotype mean?

Answer 1

Phenotype refers to traits that are physically expressed. ( Can be seen visibly)

Eg. Eye colour, colour of flower petals, shape of seeds.

Genotype simply refers to the genes that code for the traits.

Answer 2

What Does Phenotype Mean

Answer 3

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 some 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.

Nevertheless, because phenotypes are much easier to observe than genotypes (it doesn't take chemistry or sequencing to determine a person's eye color), classical genetics uses phenotypes to deduce the functions of genes. Breeding experiments can then check these inferences. In this way, early geneticists were able to trace inheritance patterns without any knowledge of molecular biology.

The interaction between genotype and phenotype has often been described using a simple equation:

genotype + environment → phenotype
A slightly more nuanced version of the equation is:

genotype + environment + random-variation → phenotype
An example of the importance of random variation in phenotypic expression is Drosophila flies in which number of eyes may vary (randomly) between left and right sides in a single individual as much as they do between different genotypes overall, or between clones raised in different environments.

A phenotype is any detectable characteristic of an organism (i.e., structural, biochemical, physiological and behavioral) determined by an interaction between its genotype and environment (see genotype-phenotype distinction and phenotypic plasticity for a further elaboration of this distinction).

According to the autopoietic notion of living systems by Humberto Maturana, the phenotype is epigenetically being constructed throughout ontogeny, and we as observers do the distinctions that define any particular trait at any particular state of the organism's life cycle.

The idea of the phenotype has been also generalized by Richard Dawkins to include effects on other organisms or the environment in The Extended Phenotype.

Answer 4

Phenotype is the outward manifestation of ones genotype (genetic make up) as it interacts with the environment.

So phenotype could be a physical trait, such as skin color or fur spotting pattern, or it could be a biochemical trait (ability or inability to metabolize lactose) or it could be a complex trait like intelligence.

Intelligence is also an example of how phenotype is a product of both genes and environment since the richness of a childs surroundings are known to produce adults with higher intelligence. Another example is turtles whos sex is determined by the temperature at which their eggs were incubated.

RE:
what does the term phenotype mean?

Answer 6

A phenotype is the visible characteristics of an organism resulting from the interaction between its genetic makeup and the environment.

Answer 7

phenotype is what physical traits a person has, traits you can see. Genotype is on the inside, the genes the person has that express or cause the phenotype.

Answer 8

phenotype is the physical expression of a particular trait in an individual.A phenotype therefore is the outward expression of our internal genetic code.

Answer 9

It means a physical characteristic influenced by genes. See, genes are really complicated by nature; a person's height alone is subject to an incredible number of genes that interplay in complex ways. But, no matter how complex the "genotype" is (or genetic makeup for that trait), the "phenotype" is always as simple as "six foot two", or "five foot seven" or whatever.

Answer 10

It is the type that is expressed. If a person has a gene for blue eyes and one for brown (brown being dominant), the phenotype is brown eyes because that is the eye color the person will have.
