Genetics Study Test With Answer Sheet Page 2

6) How do they relate? Explain how each of the two terms below relate to each other in a sentence.

a. DNA and Chromosomes (example: DNA and chromosomes relate to each other because

chromosomes are made of DNA).

b. DNA and Genes

DNA makes up genes.

c. Genes and Alleles

The options or choices for the genes are called alleles.

d. Genes and Chromosomes

Genes are segments or pieces of a chromosome.

7) In 2-5 sentences, put the pieces together and explain the complete relationship between DNA, Genes,

Alleles, and Chromosomes.

Chromosomes are made of segments of genes, which have options known as alleles. Genes are made of

DNA which contains the code for our inherited traits.

8) Develop an analogy to explain the relationship between DNA, Genes, Alleles, and Chromosomes.

If the Nucleus is a library, the Chromosomes would be the shelves. The Genes would be the books and the

Alleles would be the genre of book. The DNA would be the words.

9) Fill in the chart below with any examples (just like p7 in Notes)

Gene

My allele

Someone else’s allele

Eye Color

Ms. Bland - brown

Ms. Green – blue

Hair Color

Ms. Bland - brown

What did Gregor Mendel discover? Why is this discovery important in our lives today?

10)

Dominant and recessive traits and the role of genes. Genetic counselors can trace how a disease is

passed down in a family, and help people decide whether or not to have children.

What did Rosalind Franklin discover? Why is this discovery important in our lives today?

11)

She took the first x-ray photo of DNA, which showed that DNA is a spiral. Understanding the

structure of DNA has led to modern medical breakthroughs like genetic engineering and

cloning.

What did Francis Crick and James Watson discover? Why is this discovery important in our lives

12)

today?

He was on the team that discovered the structure of DNA, including the double helix shape

and the base pairs. Understanding the structure of DNA has led to modern medical

breakthroughs like genetic engineering and cloning.
