Heredity
patterns
of
traits
Can you
see the
strands
of DNA?
What
are
these?
• A chromosome stained in order to see
the striping pattern of some of the
genes.
Which type
of
microscope
was used to
take this
picture?
What is this
called?
Is it a boy or
girl?
Are there any
chromosome
problems?
Is it a boy or girl?
Are there any chromosome problems?
• Is it a boy
or girl?
• Are there
any
chromosome
problems?
Let’s do a
karyotype!
Is it a girl
or boy?
Who
could it
be?
Who is
this?
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.
