Heterozygous:
An individual having different alleles at one
or more genetic loci.
[Your plant is to be said heterozygous for one
feature when the genes of the responsible gene
pair are unequal.]
Phenotype:
An organism distinguishable from others by
observable features.
[How your plant looks is the phenotype. It is
the summary of all the features you can see on
the outside of your plant. It can also be smell
and taste.]
Genotype:
The genetic constitution of an individual, esp.
as distinguished from the phenotype; the whole
of the genes in an individual or group.
[How your plant looks like inside, which
features it can possibly inherit - you can't
see those - is called the genotype. It is the
summary of all genetic information which your
plant carries and can inherit to its
offspring.]
