Phenotype is the displayed characteristics of the organism, as opposed to the genotype, which is the gene sequence of the organism. Phenotype is important because it includes everything that the organism can do. Whether a plant is pink or red, an example of phenotype, can influence whether or not a bee will be attracted and pollenate it. The presence of cystic fibrosis, a debilitating disorder in humans, is caused by genotype but expressed through phenotype, and can be the difference between death at twenty or a long life to eighty.

Why natural selection acts on the phenotype rather than genotype?

natural selection is a passive prosess . the mechanism of some individuals to be selected more than others is because they fit their environment more. and phenotype shows the fitness .

How do you determine a phenotype when the genotype is different but the phenotype is the same?

You look at the offspring. Offspring of a heterogenous match are going to have different phenotype percentages than those of a homogenous match.


Phenotype can be affected by genotype and what?

Phenotype is the way a specific trait is displayed by the organism. Genotype is all the genetic information present at the gene locus on the chromosome pair. If the phenotype is recessive the genotype will be designated by two lower case letters. Ex. aa is black If the phenotype is dominant the genotype could be designatedtwo upper case letters or one upper case and one lower case letter. Ex. Aa or AA is red.


Which of the following statements about a gene that shows maternal effect inheritance is true?

A gene that shows maternal effect inheritance is one where the phenotype of the offspring is determined by the genotype of the mother, rather than the offspring's own genotype. This means that even if the offspring carries a certain genetic variant, it will only display the phenotype associated with the mother's genotype.


Why is a persons phenotype harder to predict than a persons genotype?

Because peoples appearances changes as their body changes.


Using the terms dominant recessive explain the difference between genotype and phenotype?

No, I think you have your terms confused.The terms "dominant" and "recessive" are applied to alleles of a genotype. A genotype is an expression (using upper- and lower-case letters) that shows what alleles an organism has for a particular locus. The two alleles (in most cases) inherited (one from mother and one from father) can either be dominant or recessive. The recessive allele is not fully expressed in the presence of the dominant allele and is only expressed when there are two recessive alleles. The genotype could be called "recessive" I suppose if the genotype is homozygous recessive. But remember that two recessive alleles as a genotype is only one possibility - in which case you can't say the "genotype is recessive".The phenotype is dependent on the genotype. If present, the dominant alleles (in simple Mendelian genetics) will determine the phenotype - what the organism's trait or characteristic is. The phenotype will never be what is coded by the recessive allele unless the genotype is two recessive alleles.


Is phenotype the way an organism looks and behaves a result of its genotype?

Yes. the phenotype is the visible manifestation of a genotype. In the example of fruit flies, if red eyes are dominant and white eyes recessive, than the genotypes "AA" and "Aa" will give a dominant phenotype of red eyes. Conversely, a recessive "aa" will give a phenotype of white eyes.


Does a Tt plant have the same genotype as a TT plant?

Nope! TT is the dominant phenotype (what ever it may be) and tt is the recessive phenotype (what ever that may be).So say T is the allele for Tall plants, t is the allele for short plants. TT would be show the tall phenotype while tt would show the short phenotype. If the genotype was Tt, the phenotype would be tall as well because the T is dominant and masks the phenotype of t (short plants).


Dominance that occurs whenever the hybrid genotype produces a new intermediate phenotype?

When a heterozygous genotype (two different alleles) results in an intermediate phenotype, this is either codominance or incomplete dominance. If it is codominance, then both alleles are expressed together in the phenotype. If it is incomplete dominance, the two alleles produce a blended phenotype rather than both alleles being expressed together.


Why does natural selection act on phenotype rather than genotype of an organism?

This seems to be an odd question to ask... Unless I'm mistaken, the phenotype of a given organism is governed by its genotype, and changed a fair amount by the organism's environment. Consider the following circumstances: Organism A has a long set of arms, and has a "long arm" allele. Organism B has short arms and a "short arm" allele. For example, A's genotype has the "long arm" allele, and seen in its phenotype it has long arms. The converse is true for B. Judging by your usage of technical terms in your question, I'm sure I don't need to tell you that A will out-compete B, assuming they are in a food-is-up-high environment. So, A will end up with more offspring than B, again assuming that A and B are members of different species. Eventually organism A will become prevalent, and natural selection will have caused there to be more organisms with the "long arms" phenotype, and the "long arm" allele in their genotype. In summation, Genotype governs Phenotype, and the best geno- and phenotypes will be chosen by natural selection. By an organism having a superior phenotype, it also has a superior genotype.
