In-Depth Information
Genes:
Each of the units of heredity which are transmitted from parent to
offspring in gametes, usually as part of a chromosome, and control or
determine a single characteristic in the offspring.
[There are genes responsible for each feature of your plant to be
inherited, for leaf color, stem structure, texture, smell, potency, etc.]
Alleles:
Any of a number of alternative forms of one gene.
[For example the Gene for purple bud color may have 2 forms, one for
purple and one for dark red.]
Homozygous:
An individual that has identical alleles at one or more genetic loci,
which is not a heterozygote and so breeds true.
[Your plant is to be said homozygous for one feature when it carries in
its responsible gene pair the same gene twice, which means both genes
of the gene pair are equal.]
Heterozygous:
An individual having different alleles at one or more genetic loci.
[Your plant is said to be heterozygous for one feature when the genes
of the responsible gene pair are unequal.]
