Phenotype and genotype?

Question

Distinguish the difference between phenotype and genotype, along with an example.

Answer 1

A phenotype is a trait that is visable to the eye.
A genotype is what the genetic makeup is.
For example, lets us Mendal's work on the pea plant.
He had some pea plants that were tall and some short right? well these are phenotypic attributes. You get a gene from each parent. so you either get a tall gene "T" or a short gene "t" from each parent depending on the parents genotype (do you know how to do a punnett square?) Any way, what it boils down to is you can have a recessive short offspring only if both give a recessive "t" but you can have a tall offspring as long as one of the parents give a dominant "T". They Genotypes of tall plants can either be Tt or TT and phenotypically they would look the same but thier genotypes would be different. A short plant would have the outward short appearance (phenotype) and have a genotype of "tt". This is the same for rough or wrinkled seeds, ect...What they look like is the phenotype, but what the actual genetic makeup is, well that is the genotype.

Answer 2

Genotype is the genetic makeup of an individual for some specific trait, and phenotype is the physical manifestation of that genotype.

So, if a person can roll their tongue (their phenotype), their genotype might be RR or Rr. If they cannot roll their tongue, their genotype would be rr.
