Describe a genotype.
The genetic makeup, or set of alleles, of an organism.
For example, we distinguish between an organism's appearance or observable traits as the phenotype and the genetic makeup as the genotype.
In the case of flower color in pea plants,
PP and
Pp have the same phenotype (appearance of the purple color) but 3 different genotypes (
PP - purple,
Pp - purple, and
pp - white).
P represents the dominate allele and
p represents the recessive allele.
