What is the study of genes and traits that parents pass on to their children?

What is Heredity?

100

What is a histogram?

A graph using bars to show the frequency of a qualitative variable, such as hair color or eye color.

100

What is an example of a dominant and recessive trait?

Dominant: Brown eyes

Recessive: Blue eyes

100

What is a code?

Symbols, letters, words, or drawings used to communicate information.

100

What does heterozygous mean?

When you inherit two different alleles for a single trait. (Bb)

200
What is an example of a physical trait?
What is Hair color, eye color, ear shape?
200

Why is the use of graphs important for scientists? (What do they show us?)

The variation amongst a population.

200

What are Punnett Squares used for?

To help predict variations and probabilities, for example eye color.  

200

What is morse code?

A system of communication with long and short duration sounds.  Each letter of the alphabet has a unique series and sound.  In written form, it contains dots and dashes.  

200

What does homozygous mean?

When you inherit the same allele for a single trait (bb, BB)
300

What are genes?

What are Segments of DNA that provide the instructions for specific traits?

300

In addition to hair color and eye color, what trait can be inherited?

What is height, ear shape, lip shape?

300

What are different forms of the same gene? (We inherit one from our mother and one from our father)

What is an allele?

300

What is a cipher?

A key that explains what coding symbols mean.

300

What is the structure of DNA called?

What is a double helix?

400

Who are the only people that have the same DNA?

Who are twins?

400

What is the most common eye color in our classroom?

Brown 

400

How many dominant genes do you need in order to have brown eye? 


one 

400

What was travelers code used for?

To warn travelers when they were traveling.  

400
If Carlos has one blue eye gene and one brown eye gene, what color eyes does he have? Why?


Brown, because it is a dominant trait.  

500

What are genes often referred as?

What are "units of heredity"? 

500

When we looked at the map of eye color distribution around the world, how come so many people have brown eyes?

It is a dominant gene and more common.
500

How many blue genes are required for a person to have blue eyes?

Two

How are codes similar to DNA coding?

If a code is changed, it can alter the result, which is similar to DNA because if the formation of DNA is altered, it can lead to a health condition.  

500

What was the mnemonic for the base pairs of DNA? (from the rap song)

200 extra if you can name them.  

GCAT 

G:Guanine C:Cytosine A:Adenine T: Thymine
