(upbeat music) Good morning amazing students of Arkansas.

I am Trey Suskie and today, we will be identifying the similarities and differences in traits shared between offspring and their parents or siblings.

First, let's discuss traits.

What are they and how do we get them?

That's right.

They are inherited or passed down to us from our parents.

What are some examples of traits that are passed down from your parents?

Yes.

These can include eye color, hair color and texture, skin tone, blood type, freckles and dimples, just to name a few.

Now that we understand traits and how they work, how are they passed down, and what are the chances you will get a specific trait?

The chances of getting a trait is based on whether the trait is dominant or recessive.

Now, what do these terms mean?

Dominant traits will always override or hide recessive traits, even if only one parent has it.

Recessive traits will be hidden by dominant traits, so both parents must have the recessive trait for it to show up.

But even then, it's not guaranteed to show up in the offspring, or babies.

What are some examples of recessive and dominant traits?

Dominant traits include brown or black hair and brown eyes.

Do you or anyone in your family have these traits?

What about blond or red hair or blue or green eyes?

If you have these traits, then recessive traits have been passed down to you.

If you have freckles, you have the dominant trait.

Dimples are also dominant.

Take a look at these examples we have explored, plus a few more.

So we have widow's peak and no widow's peak.

Widow's peak is dominant.

No widow's peak is recessive.

Next, we have freckles and no freckles.

No freckles is recessive and if you have freckles that's dominant.

Now your eye color, if it's brown or blue, brown eyes are dominant and blue eyes are recessive.

Next, we have no cleft chin or a cleft chin.

If you don't have a cleft in your chin, then it's recessive.

If you do have a cleft, it's dominant.

Now look at attached ear lobes versus unattached ear lobes.

If you have unattached, they are dominant.

If you have attached, they are recessive.

Finally, let's look at dimples versus no dimples.

Dimples are dominant.

No dimples are recessive.

What a great job, students.

Thank you for tuning in and have a fantastic rest of your day.

You're a great student so we know that you can do it.

Rise and shine.

Get up off your feet.

Ah, ooo, ooo.

It's time to rise and shine.
