Chromosomes are structures in the nucleus of cells that consist of DNA.

CHROMOSOMES

There is a X and Y chromosome. What do you notice?

X Y

These TWO chromosomes determine gender!

You have to have a combination of 2:

Males are XY

Females are XX

You get one from your mom and one from

your dad.

But, what controls the traits?

THE X and THE Y

Small dark bands mark the chromosomes into sections called genes.

The GENES

A gene controls the trait.Examples of traits are hair color, eye color, and

your fingerprint.What fingerprint do you have?

Everyone is identical, even twins!

If you lose skin on your fingertip, it grows back

in the same print.

Let’s see what pattern you have!

Rub pencil over your fingertip and touch it to

your paper.

A trait can be homozygous or heterozygous.

You have a genotype , which has two alleles.A genotype is written as AA, Aa, or aa.The letter represents the trait.A capital letter means the trait is DOMINANT

and will always be expressed – AA or AaTwo lowercase letters mean the trait is

RECESSIVE and will show – aa.
