Phenotype is the observable characteristics shown by an organism it is affected by both genotype (alleles and genes) and environment. If ,for example, a boy inherited white-colour skin from both his mother and father but he spent a lot of time in the sun then he's skin will get darker. Or if his parents were both tall but he didn't play any sports or he didn't eat healthy food so he didn't receive the nutrients needed to switch on these genes he'll be short.

∙ 14y agoNo it is not. Although genotype does affect phenotype, the environment in which the organism lives also will affect the phenotype.
Wiki User
∙ 12y agoBecause Genotype is a make-up of an organism and phenotype is the apperance of an organism.
Wiki User
∙ 13y agothe environment can also affect phenotype.
an example: a person with naturally brown hair; when exposed to a lot of sunlight it can change to a lighter shade
Wiki User
∙ 10y agobecause the alleles are the ones that make the genotype
Wiki User
∙ 10y agoGenes are also regulated (turned on and off) based on the physiological environment, which is dependant to some degree on the external environment.
Wiki User
∙ 9y agoGenotype is not the only factor that affects phenotype, because the environment affects phenotype as well. Another term for genotype is genetic makeup.

How is incomplete dominance expressed in phenotype?
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
What are the phenotypes and genotypes of the offspring from the mating of a person with type B blood with a person with type O blood in codominance?
The offspring blood type with parents that have O and B blood types would come out with O positive. This is taught in biology. Based on the details of the question this initial answer is incorrect. Type O is not a dominant characteristic merely a common one. A person with type B blood could have a genotype of BO or BB so there are two potential answers to this question. The parent with O type blood can only have an OO genotype. If the parents are BB and OO then all offspring will be type B phenotypically and their genotype will be BO. If the parents are BO and OO then 50% of the offspring will have the BO genotype and 50% will have the OO genotype. Phenotypes will be B and O respectively. Since the question did not include any mention of the RH factor there is no way to determine that the offspring would be positive or negative. True codominance in blood types really only shows up with the AB genotype where the phenotype of the individual matches the genotype and the person has both A and B blood factors.
How can a genotype change a phenotype?
no not always due to some phenotypes having more than one gene sequence that affects it, eg; the base sequence for a certain enzyme's synthesis could be TTT but by substituting a T with a C to make TTC in mutation could still be a code for the same enzyme...
What is the difference between phenotypes and genotypes?
Genotype are the unseen differences in genetic combinations of an individual. Phenotypes are the expressed and seen differences of an individual.A genotype is the genetic makeup of an organism with reference to a single trait, set of traits, or an entire complex of trait; that is, genotype is the type of genes you have. A phenotype is the physical characteristic of an organism. So the genotype decides the genetics and inherited traits of an organism, but phenotypes refer to the actual display of these traits. Genotypes are decided by inherited genes, while phenotypes are determined by the effect of environmental factors as well. The more complex a biological process, the more is the effect of environmental factors on it and therefore the chances of a predominant phenotype.For example, say recessive allele t codes for albinism (a congenital disorder) and dominant allele T is normal. Two individuals have different genotypes: TT and Tt. Because they both have an allele T, neither have albinism; therefore, they have different genotypes but the same phenotype. An individual with a genotype tt would have albinism and would therefore have a different phenotype than the previous two.Another example: Identical twins have the same genes and the same genotype. Every now and then a gene in one of the twins will be expressed differently from the gene in the other twin. They will have different phenotypes. So phenotype is a fancy word used when a gene works one way under certain conditions and a different way under other conditions.An easy way to remember that (from what I've learned from my science teacher) is to think "Pheno" as "Photo", like if you take a picture, you'll only be able to see the outside of somebody; what they look like..In more detail:Take alleles R and r. If R and R display a "complete dominance" relationship, then RR , Rr, and rr are different genotypes, but two are the same phenotype. RR and Rr display the same trait because R is completelycovering up r's trait, but rr will show the recessive trait.EX: A flower with R as a red trait and r as a white trait has the following phenotypes for each genotype:RR: redRr: redrr: whiteAdditional information:If R and r display a "codominance" relationship, then RR, Rr, and rr are different genotypes and phenotypes. RR shows the dominant trait, while rr shows the recessive trait. Rr shows a combination of the two, as if the two were dominating cooperatively.EX: A flower with R as a red trait and r as a white trait has the following phenotypes for each genotype:RR: redRr: red and whiterr: whiteIf R and r display a "incomplete dominance" or "incomplete inheritance" relationship, then RR, Rr, and rr are different genotypes and phenotypes. RR shows the dominant trait, while rr shows the recessive trait. Rr shows when R incompletely dominates r, allowing some of its qualities show. EX: A flower with R as a red trait and r as a white trait has the following phenotypes for each genotype:RR: redRr: pinkrr: white
How are the genotypes of parents related to the genotypes and phenotypes of the offspring?
alleles are variations of genes
Why is genotype not the only factor that affects genotype?
cha cha has the answer ! :D
How are the genotype and phenotype of parents related to the genotype and phenotypes of offsprings?
The parents can pass on only the alleles of their genotypes to their offspring. Therefore, the offspring genotypes and phenotypes are dependent solely upon the alleles inherited from the parents.
How differences in genotypes cause variations in phenotypes?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
How are Genotype phenotype different?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
Why phenotypes don't always express its entire genotype?
Phenotypes are the entirety of the observable traits. Genotypes are the instructions in the genetic code. Dominant alleles override the recessive alleles, making only the dominant alleles expressed.
Does a genotype determine phenotypes?
The genotype against the immediate environment and developmental processes. Each organism has a unique environment too. Think about it. Even identical twins are not totally their genotype because they are subject to not only the same environment, usually, but the unique experiences and formative processes of their unique environment.
How is incomplete dominance expressed in phenotype?
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
What are the similarities and differences between phenotypes and genotypes?
The genotype of an organism is the group of characteristics derived from a combination of heredity and environmental factors. Genotype is based on genetic factors only. phenotypes are the genes that an organism carries. For example, the gene for blue eyes could be b and the gene for brown eyes could be B. Bb is a genotype. Phenotype is the trait that show up. Since brown eyes are dominant, the phenotype of Bb would be brown eyes.
What is the only factor that affects the range of a projectile?
Gravity
How are codominant alleles and incompletely dominant similar?
Codominance and incomplete dominance can only exist if the genotype has heterozygous alleles.
What are the phenotypes and genotypes of the offspring from the mating of a person with type B blood with a person with type O blood in codominance?
The offspring blood type with parents that have O and B blood types would come out with O positive. This is taught in biology. Based on the details of the question this initial answer is incorrect. Type O is not a dominant characteristic merely a common one. A person with type B blood could have a genotype of BO or BB so there are two potential answers to this question. The parent with O type blood can only have an OO genotype. If the parents are BB and OO then all offspring will be type B phenotypically and their genotype will be BO. If the parents are BO and OO then 50% of the offspring will have the BO genotype and 50% will have the OO genotype. Phenotypes will be B and O respectively. Since the question did not include any mention of the RH factor there is no way to determine that the offspring would be positive or negative. True codominance in blood types really only shows up with the AB genotype where the phenotype of the individual matches the genotype and the person has both A and B blood factors.
