Phenotype and Genotype

Question

I need a simple explaination of the difference between a Phenotype and Genotype and what the importance is in considering genetic disease.

I have information on it but just need clarification for my own theory.

Thanks for your help.

Answer 1

genotype is the genetic make-up of an organism, phenotype is how it presents itself in the organism physically.  

Answer 2

the easiest way to remember as being teach by my lecturer..

Phenotype = Physical = you can see

Genotype = Gene = you cant see

PEACE =D

Answer 3

genotype- is like the genetic make-up of a person (so like the genes that make them well them basically)

phenotype- is like the physical appearance.

i cant exactly answer the other question.

Answer 4

pretty much everyone else is right!!

gentotype is the arrangement of genes (e.g. the genes for blue eyes)

phetotype is the appearance these genes represents (e.g. someone with blue eyes- what you see)

with regards to genetic disease i would say understanding the genotypes of a particular genetic disease will help you see what faults lie within the gene- if you look at the genotype of a genetic disease and you see a certain gene contains a mutation then you could treat it or research the treatment at least...

hope this helps, but everyones answer is spot on!!!

Answer 5

genotype: genetics/genetic make-up of an organism.

phenotype: what they look like, so their physical characteristics.

to remember just remember gen=genetics

i dont understand the next part though, the importance in considering genetic disease.....maybe the phenotype tells us the symptoms of it and the genotype confirms it through tests?

Answer 6

Genotype: The Genetic makeup of a person or thing. Think gen- genetic.

Phenotype: Physical, outer appearance. Think ph- physical.
