Do Now 11/8 – It’s Friday! What is a mutation? What is a trait? What does inherited mean?

Fun-Fact Friday! • Palm trees are technically not trees, they're grass. • By the time you feel thirsty, your body is already dehydrated. Drink more water! • There has not been a bearded President of the United States since 1893. • Millions of people have armpits that never smell due to a gene mutation that stops them from producing sweat. • The division sign "÷" is actually called an obelus.

Think for a second about the most crazy thing you have ever seen…

when something like THIS could be possible… Imagine in the future…

The future is now…

How did the scientists do it?

GENETICS

Today’s Objective • Student will be able to analyze various inherited traits and compare prevalence in the classroom to the world.

Inherited Traits • Spend the next ~5-7 minutes answering the questions given with your partner • When finished, come up to the board and place a tally in the correct slot for each trait

Statistical analysis • What are Statistics? • the practice or science of collecting and analyzing numerical data in large quantities, esp. for the purpose of inferring proportions in a whole from those in a representative sample. • In our own words? • The use of data to learn something about a population

Let’s do some statistics • Find the percentage of the class that has each trait and write that percent next to each on your paper. • How to find percent: • Count up the number of tallies for a particular trait • Divide that number by the total number of students in the class • Ex. There are 5 people with freckles and 25 in the class, so 5/25 = 0.2 • Multiply that number by 100 • Ex. 0.2*100 = 20% • That is the percentage of people in the class with that trait

How does it compare to the population? • Earlobes- ~16% have attached earlobes • Tongue rolling – ~70% can roll their tongue • Dimples – 25% have them • Hitchhiker’s Thumb – 25% have it • Second toe – 20% of with a longer second toe • Hand clasping – 60% Left Thumb Dominant • Widow’s Peak ~25% have it

Now… What if you could use this information to design your own child?
