1. Define Probability.
The likelihood that a particular event will occur
normally written as a number value
example: Fraction, Percent, Ratio
Example:
2. What is the probability a coin will land on heads?
Fraction
Percent
Ratio
3. T/F probability can give an exact prediction. EXPLAIN…
It is only an educated prediction; no one can predict the future!
Mendel and Probability
4. Mendel’s F1 generation (the hybrids produced from the purebred parents) genotype
(what was their allele/letter combination):
Tt
5. When they self-pollinated, what was the outcome?
a. How many tall?
i. Fraction: ¾
ii. Percent: 75%
iii. Ratio: 3:4 or 3 to 4
b. How many short?
i. Fraction: ¼
ii. Percent: 25%
iii. Ratio: 1:4 or 1 to 4
6. Mendel was the first scientist to recognize he could use the principals of
__probability__ to predict the results of genetic crosses.
