Final Jeopardy Question
DNA &
Genetics
Researched genetics by controlling the pollination
of pea plants and tracked the traits in their offspring.
Summarize Gregor Mendel’s
experiements.
Back to the Game Board
10 Point Question
He controlled the breeding of plants with crosspollination and he observed hundreds of plants.
Determine two characteristics of
Mendel’s experiments that helped
him reach useful conclusions.
Back to the Game Board
20 Point Question
Two factors control each trait & some inherited
factors can block others.
What was Mendel’s two main
conclusions about inherited
traits.

Recessive
A dairy farm bred a true-breeding
hairless cow with a true-breeding
cow that had hair. The offspring
had hair. What word best describes
the hairless gene?

Incomplete dominance
Enrique has a red-flowering camellia
plant and a white-flowering camellia
plant. The next spring, a pinkflowering camellia plant grows. What
type of interaction does the pink
flowering plant show?

40 Point Question
DNA is an organism’s entire genetic material
and RNA carries instructions for making
proteins.
What is the difference between
DNA and RNA?
Back to the Game Board
10 Point Question
Proteins express traits. Mutations can alter
proteins and they change the way the traits
are expressed.
How do mutations affect traits?
Back to the Game Board
20 Point Question
Translation if the entire process of making a
protein from RNA. Transcription is the first
step in this process.
Relate RNA to translation and
transcription.

genes determine the phenotype
of a trait?
