No, genotype actually determines phenotype.
It is a false statement that "phenotype determines genotype". In fact, it is the opposite. A genotype is the genetics or "instructions" that determine the phenotype. The phenotype is the actual appearance, ex: blue eyes, that is created by a given genotype.
Yes you can accurately determine an organisms genotype by observing it's phenotype, however some phenotypic traits resulting from homozygous or heterozygous combinations of alleles, may make the prediction impossible.
Do you mean the phenotype?The phenotype is not only the organisms appearance but also the organisms behavior.
phenotype
The phenotype.
The FALSE statement is "A phenotype determines genotype." In reality, it is the genotype that determines the phenotype, as the genetic information (allele combinations) present in an individual's DNA influences their observable traits.
Phenotype does not determine genotype. Actually a genotype includes an organisms entire hereditary information. A phenotype is simply the organisms actual observed properties including appearance, development and behavior.
No. It is possible for the reverse to be true, two organisms can have the same phenotype but a different genotype. This is because the phenotype is what you will see on the outside whereas the genotype is the combination of alleles and since this determines the phenotype, two organisms with the same genotype will have the same phenotype. So, basically, no. Actually 2 organisms can certainly have different phenotypes with the same genotype--this refers to the concept of penetrance. Some people can have the gene for a condition but never show symptoms. An excellent example of this is the disease neurofibromatosis. This disease has very variable penetrance in which a child of an affected parent may show no signs of the disease, but then have a child with a severe form.
