What

is

genetics?

“Genetics

is

the

study

of

heredity

the

process

in

which

a

parent

passes

certain

genes

onto

their

children.”

(http://www.nlm.nih.gov/medlineplus/ency/article/002048. htm)

What

does

that

mean?

Children

inherit

their

biological

parents’

genes

that

express

specific

traits

such

as

some

physical

characteristics,

natural

talents,

and

genetic

disorders.

Inheritance

The

inherited

traits

are

determined

by

genes

that

are

passed

from

parents

to

children.

A

child

inherits

two

sets

of

genes—one

from

each

parent.

A

trait

may

not

be

observable,

but

its

gene

can

be

passed

to

the
