Tomorrow we will have a test for our Heredity and Genetics Unit.
The topics we have covered in this unit include:
- How genes play a role in an organism's characteristics.
- The differences between inherited, acquired, and environmentally influenced characteristics.
- The relationship between genotype and phenotype.
- The three different ways that alleles can interact with one another: in a dominant/recessive relationship, a codominant relationship, or an incompletely dominant relationship.
- The differences between innate behaviors (inherited) and learned behaviors (acquired).
- The different types of seasonal behaviors: migration and hibernation for animals, and the leaf cycle for plants.
- The presence of invasive species and the role they plan in ecosystems.
Here are some helpful links for review/understanding:
- - A website explaining the differences between genotype and phenotype:
- http://evolution.berkeley.edu/evosite/evo101/IIIA1Genotypevsphenotype.shtm
- A great website explaining the use of Punnett Squares and how they work:
- http://anthro.palomar.edu/mendel/mendel_2.htm
- A website explaining the differences between CODOMINANCE and INCOMPLETE DOMINANCE
- http://www.hobart.k12.in.us/jkousen/Biology/inccodom.htm
- Information on invasive species:

Here are some resources to help you study:
- - Heredity Vocabulary Review Game (there are 2 words that we didn't study)

- Review of Heredity and Genetics (Including genotypes, phenotypes, and Punnett Squares):

Extra Credit Opportunity:
DIRECTIONS: Either print out these 2 problems OR write them on a sheet of paper and bring it to class complete.
1. SpongeBob’s aunt is famous around town for her itty, bitty stubby nose! She recently met a cute squarepants fellow who also has a stubby nose, which is a recessive trait. Would it be possible for them to have a child with a regular long nose? Why or why not? Create a Punnett square to help you answer this question.
2. If SpongeBob’s aunt described in #7 wanted children with long noses, what type of fellow would she need to marry in order to give her the best chances? Create a Punnett square to help you answer this question.
Hope these are helpful.
Happy studying!
Ms. Ryland
