Gene Coin Toss

Gene Coin Toss
Problem: Is the probability of the coin outcomes accurate?
Hypothesis: Yes, if the statistics of tossing two coins is correct, then the
outcomes will prove that.
*Dependant: the outcome
*Independent: the statistics of tossing two coins
*Control: the coins that you use, the cup, the surface that it lands on,
and the number of times that you shake the cup.
*1 cup
*Two coins that are the same (nickels, dimes, pennies, etc.)
First, gather all of your materials. (1 cup and 2 coins) Next, make your
data table. It should look like the one on the following page. Each
combination represents a genotype. Heads, heads is homozygous dominant,
tails, tails is homozygous recessive, and heads, tails is heterozygous. Next,
put your coins into the cup, shake it 5 times, and on the 5th time, dump the
coins. Record your results on the tally column in your data table. After
repeating this process 10 and 50 times, recording your results each time,
analyze and draw conclusions.
Data and Observations:
Conclusion: My hypothesis was correct; my statistics were shown by my
Discussion: I learned that statistically, the probability of something is
actually close to the real outcome. And you could use it for lots of stuff in
life, like playing cards. And it would be helpful if you were a breeder, like a
racehorse owner, and you could use it to make the fastest foals or
something. Probability has many uses.
