Genes and Natural Selection

A slight difference in an inherited trait between individual members of the same species.

• variations
• adapatations
• homologous structures
• analogous structures

An inherited trait that increases an organism's chance of surviving and reproducing.

• variation
• adaptation
• vestigial structure
• mutation

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy

The term that relates to physical characteristics that are studied in genetics.

• traits

• offspring

• generations

• hybrids

What is a protein?

• type of molecule that carries inherited information passed from parents to offspring.

• A segment of DNA that contains the instructions of building proteins

• A type of molecule that makes up much of an organism’s structure and helps it function

• A cell structure that contains an organism’s DNA.

A cell structure that contains an organism’s DNA is called

• Chromsome

• DNA

• Protein

• Gene

Where are chromosomes located?

• Nucleus of a cell

• Mitochondria of a cell

• Chloroplast of a cell

• In the blood

What did the ALX1 gene control in finches?

• The ALX1 gene contains the instructions for building a protein that helps control the growth and development of the finch’s face

• The ALX1 gene contains the instructions for building a protein that helps control the growth and development of the finch’s blood type

• The ALX1 gene contains the instructions for building a protein that helps control the growth and development of the finch’s feet

• The ALX1 gene contains the instructions for building a protein that helps control the growth and development of the finch’s body and wings.

Which of the follow correctly describes genes, proteins and traits?

• Genes contain information on making proteins and proteins control the expression of traits.

• Proteins contain information on making genes and proteins control the expression of traits.

• Proteins don't affect the expression of genes

• Proteins produce genes which control the expression of traits

How are traits passed on from parent to offspring?

• DNA

• Cells

• Proteins
