3. Punnett Square
Phenotype
Genotype
Homozygous
Heterozygous
Conominance
A punnett square is a chart that shows all the possible combinations of alleles that can result from a genetic cross.
An organism’s phenotype is its physical appearance, or visible traits.
An organism's genotype is its genetic makeup, or allele combination.
An organism that has two identical alleles for a trait is said to be homozygous.
An organism that has two different alleles
For a trait is heterozygous.
For some alleles, an inheritance pattern called codominance exists.

4. If you would like to follow along please flip to the pages in your notebook that are listed below the slide

5. Each time you flip a coin there are two possible ways the coin can land so the probability would be 50, 50. The laws of probability predict what is likely to occur not necessary what will occur. The more tosses you make the closer your actual results will be to the result predicted by probability.

6. Well that was interesting. I hope it helped you understand more
Well that was interesting. I hope it helped you understand more. Now we are done with our probability unit so we will get started on our Punnett square unit! Yay after that we will have a heredity lesson and then we will be done and someone will go next YAYYAYYAYAY for them!!!!

8. Next slide will be a video explaining what probability is in a clearer way
SING ALONG

9. Please take out a pencil and Abby will pass out papers (-;
Sorry on the worksheet there is a mistske. PLease ignore it ( katie’s fault nothing to do with abby)

10. R r
The diagram shows how to make a Punnett Square. In this cross, both parents are heterozygous for the trait of seed shape. R represents the dominant round allele, and r represents the recessive wrinkled allele. R r
RR Rr

11. Well we are done finally with the punnett square so let's get to the Heredity section.

12. So for Heredity we are just going to play a video after we might ask some questions for fun and see if you were actually listening
