A genotype is the genetic labelling for an individual characteristic. It is the type of gene they have, such as homozygous (RR or rr for example) or heterozygous (Rr). Phenotype is the physical appearance of the genotype. For example, if R is dominant for red flowers and r is recessive for white flowers then:
genotype RR== Phenotype red
genotype Rr == Phenotype red
genotype rr == Phenotype white

genotype is a description of the allels of the organism so if you describe a mutant allel and assume the rest of the animal is wildtype you are describing the genotype. The phenotype is often the effect of those genes, but is most accurately the description of a set of physical attributes or behaviors. Using PCR to amplify a gene, and then visualizing the resultant with electrophoresis turns a genotype into a pcr phenotype.

To determine the set of alleles an organism has for a given trait just by visual observation can often be difficult. In the pea plant example, for instance, plants with smooth peas might be carrying two dominant alleles for that characteristic (RR) or one dominant and one recessive allele (Rr). Geneticists use the term genotype to refer to the combination of genes that code for a trait, while the term phenotype describes the physical manifestation of that trait. Therefore, the presence of two dominant alleles for pea texture (RR) would reflect the genotype while a smooth pea indicates the phenotype.

I'll make it understandable :) :
A phenotype is a gene trait that can be observed, like blue eyes or blond hair. A genotype is the collective alleles. I am not sure what your history in biology is, but just in case: Alleles are the gene's "choices" Hope that this helps you out!

Here you go :-)
The distinction between phenotype and genotype is fundamental to the understanding of heredity and development of organisms. The genotype of an organism is the class to which that organism belongs as determined by the description of the actual physical material made up of DNA that was passed to the organism by its parents at the organism's conception. For sexually reproducing organisms that physical material consists of the DNA contributed to the fertilized egg by the sperm and egg of its two parents. For asexually reproducing organisms, for example bacteria, the inherited material is a direct copy of the DNA of its parent.
The phenotype of an organism is the class to which that organism belongs as determined by the description of the physical and behavioral characteristics of the organism, for example its size and shape, its metabolic activities and its pattern of movement

phenotype is what you look like which is determined by your genotype, the what your gene makeup is.

The genotype
genotype is the actual genetic make up of the individual.
genotype is repeated by letters EG. TTtt.
The phenotype
phenotype is observable traits.
phenotype is a description of the traits. EG. red hair with blue eyes.

genotype is the actual genes that a person carries
phenotype is the outer, inner appearence that is created when those genes are expressed
