Why is DNA important?

• it is very small and very complicated

• it serves as the blueprint for traits of all living things

• because we eat it every day for energy

Multiple Choice

How many alleles do you get from each parent?

• 1

• trait

Multiple Choice

Characteristics or features that can be passed from one generation to another is

• heredity

• trait

Multiple Choice

There is a segment of DNA that codes for every trait that a person has.

These segments of DNA are found on chromosomes and are called ________.

• Deoxyribonucleic acid

• Genes

• Heredity

• Recessive Traits

Multiple Choice

If "T" is the allele for tall and "t" is the allele for short, then Tt would produce?

• tall

• short

• medium

• not enough info

Multiple Choice

A long piece of coiled DNA found in the cells; contains genes that encode traits.

• gene

• chromosome

• trait

• DNA

Multiple Choice

What is the relationship between DNA and chromosomes?

• Chromosomes are made of DNA

• DNA is made of chromosomes

• DNA and chromosomes are the same thing.

• All of the above are correct

Multiple Choice

G = green, g = yellow
The genotype for a yellow plant is...

• GG

• Gg

• gg

• all of the choices result in yellow

Multiple Choice

Why are your chromosomes arranged in pairs?

• Scientists have no idea

• Because you get one from your mom and one from your dad

• Because pairs can divide easier

• Because DNA is awesome

Multiple Choice

What does heterozygous mean?

• An organism that has the same genes for a trait (TT or tt)

• An organism that has different genes for a trait (Tt)

• When neither gene is fully dominant; offspring is a mixture of both

• the different forms of a trait (hair color--> brown, blonde, red

Multiple Choice

How are similarities passed from parent to offspring?
