what is a genotype ???

Question

and an example:...

Answer 1

The genotype is the specific genetic makeup (the specific genome) of an individual, in the form of DNA. Together with the environmental variation that influences the individual, it codes for the phenotype of that individual. Non-hereditary mutations are not classically understood as representing the individuals' genotype. Hence, scientists and doctors sometimes talk for example about the (geno)type of a particular cancer, thus separating the disease from the diseased. While codons for different amino acids may change in a random mutation (changing the sequence coding a gene), this doesn't necessarily alter the phenotype.

Answer 3

Genotype is genetic makeup an organism has; in contrast phenotype is just the physical results of those genes being expressed. For example, a human male baby is born with a genotype of XY for its sex chromosomes. The genotype would be XY, but the phenotype is its physical male characteristics, like testes and a penis. The same applies for characteristics like eye color. "Blue-eyed" is not a genotype, but a phenotype.

Answer 4

The problem is to understand genotype and phenotype. Genotype is what genes are in an organism and phenotype is what genes get expressed in that organism.

Also study - dominant and recessive genes.

Answer 5

Genotype is the specific genetic makeup (the specific genome) of an individual, in the form of DNA.
