#3 Genes and Heredity
•Heredity is the passing of genes from one generation to the next. You inherit
your parents' genes. Heredity helps to make you the person you are today: short
or tall, with black hair or blond, with brown eyes or blue.
•Can your genes determine whether you'll be a straight-A student or a great
athlete? Heredity plays an important role, but your environment (including things
like the foods you eat and the people you interact with) also influences your
abilities and interests.

#4 - MUTATIONS
•A person can have changes (or mutations) in a gene that can
cause many issues for them. Sometimes changes cause little
differences, like hair color. Other changes in genes can cause
health problems.
•Mutations in a gene usually end up causing that particular gene
copy to not do its job the way it normally should. Since we have
two copies of every gene, typically there's still a "normal"
working copy of the gene. In these cases, usually nothing out of
the ordinary happens since the body can still do the jobs it needs
to do.
