1 Intro to genetics Biology Quiz

What is heredity?

• The study of plants

• The passing of traits from parents to offspring

• The process of photosynthesis

• The study of ecosystems

What are genes?

• Units that contain the hereditary information of organisms

• Cells that make up the human body

• Proteins that provide energy

• Enzymes that break down food

Who is considered to be the father of modern genetics?

• Charles Darwin

• Albert Einstein

• Gregor Mendel

• Isaac Newton

What is a generation?

• A set of members of a group that are born around the same time.

• A trait that appears in an organism's offspring.

• The hidden trait that is not expressed in an organism's offspring.

• The varying forms of a gene.

What is a dominant trait?

• The main trait that appears in an organism's offspring.

• The hidden trait that is not expressed in an organism's offspring.

• A set of members of a group that are born around the same time.

• The varying forms of a gene.

What is a recessive trait?

• The hidden trait that is not expressed in an organism's offspring.

• The main trait that appears in an organism's offspring.

• A set of members of a group that are born around the same time.

• The varying forms of a gene.

What was interesting about Mendel's pea plant experiments?

• He observed the inheritance of traits in pea plants.

• He discovered the structure of DNA.

• He studied the behavior of animals.

• He invented a new type of plant.

What happened when Mendel planted one tall and one short pea plant?

• All short pea plants appeared

• All tall pea plants appeared

• Half tall and half short pea plants appeared

• No pea plants appeared

What is the basis of the idea of alleles?

• Different forms of a gene

• Different forms of a cell

• Different forms of a chromosome

• Different forms of a protein

What do you know about dominant traits? (This is your own educated guess)

• Traits that are always expressed in the organism

• Traits that are never expressed in the organism

• Traits that are sometimes expressed in the organism

• Traits that are expressed only in the presence of a recessive trait
