1. Packet 8- Notes pg. 4 How likely is it that a trait is passed on to the offspring?

2. How do we know if a trait will be passed to a child?
Probability is the likelihood that an event will occur.
So if we know the genetic makeup of the mom and dad, we should be able to figure out if it is probable (how likely) and/or possible (could it) for them to pass down certain traits.
How do we know if a trait will be passed to a child?

3. How do we know if a trait will be passed to a child?
We will use a box called a Punnett Square to determine the probability that specific traits will be passed down from parent to offspring.
How do we know if a trait will be passed to a child?

4. How do we know if a trait will be passed to a child?
Monohybrid cross- a cross that involves one pair of contrasting traits.
E e
(Dad’s genotype)
(Mom’s genotype) E e EE Ee Ee ee
How do we know if a trait will be passed to a child?

5. How do we know if a trait will be passed on?
Dihybrid cross- a cross that involves two pairs of contrasting traits.
A a B b a b
