Mendel began his work
with true breeding
(purebred) pea plants.
True breeding = only
have one type of gene
that they can give to
their offspring.
Example:
True breeding tall plants
= allele pair of TT and
could only give a T (tall
gene) to their offspring
True breeding short
plants = allele pair of tt
and could only give a t
(short gene) to their
offspring.
