GENETICS
The genetic information
from your parents is
combined to make
a single cell called a
zygote
At conception, an egg from
your mother and a sperm
from your father combined
to create you. The egg and
sperm carried your parents’
genetic information (DNA)
and as the two parts
combined, your genetic
make-up was formed. Your
genetics determined how
your body would grow. If
your parents are short or
tall, you’re likely to grow
up like them.
