(14) Organisms and environments. The student knows that reproduction is a characteristic of living organisms and that the instructions for traits are governed in the genetic material. The student is expected to:

(A) define heredity as the passage of genetic instructions from one generation to the next generation;

( C )recognize that inherited traits of individuals are governed in the genetic material found in the genes within chromosomes.

4.26.11 Genetic word wall

• We will create a genetics word wall TEK 7.14• Warm up:

Reproduction:

• is done by all living things to keep their species going

Heredity:

• the passage of genetic instructions from one generation to the next generation;

Asexual reproduction:

• when there is only one parent and offspring are identical to the parent

Sexual reproduction:

• there are two parents and the offspring have traits from both the mom and the dad (diverse offspring)

Traits:

• characteristics that are inherited from the genetic material passed from parent to offspring

Genes:

• give an organism specific traits and can be found within a chromosome on the DNA

Chromosomes:

• are found inside the nucleas and contain DNA

• Recall: Gregor Mendel is the father of genetics• Summary: Mendel studied pea plants to get a

better understanding of how traits were passed down from one generation to the next

• OUT: Where can you find the genetic material in a eukaryotic cell? In a prokaryotic cell?

**use complete sentences**

4.27.11 Edusmart Genetics

• We will use edusmart to further our understanding of genetics TEK 7.14 A&C

• Warm up

• Recall: specific traits can be found on particular genes

• Summary: describe the difference of a dominate trait and a recessive trait

• Out: Gregor Mendel, the father of genetics, didn’t have a microscope to see inside the nucleus of a pea cell. Describe the method he used to study genetics.

** use complete sentences with capital letters and periods. No PRONOUNS**

4.28.11 Sponge Bob Punnet Sq

• We will use sponge bob to practice punnet squares. TEK 7.14 A&C

• Warm up:

• Homologenous: both genes are identical (RR, rr)• Heterogenous: the genes are different (Rr) • Dominate: always shows and is a capital letter • Recessive: only shows up if there are two recessive

genes ( 2 lower case letters)• Phenotype: what it looks like ( round, square, blue)• Genotype: the letters that represent the genes the

offspring have (RR, Rr, rr)

• Recall: Punnet squares help us predict what offspring will look like.

• Summary: Explain why genotypes have two letters and not one

• Out: Solve the Punnet square: Sally is a dominate homogenous brown hair and Jack is recessive homogenous blond hair. What will their offspring look like?

4.29.11 Monster gene lab

• We will create a marshmellow alien using dominate and recessive genes TEK 7.14 A&C

• Warm up:

•NEED TO FIND PAPER TO FILL THIS IN!

• Recall: dominate traits show up more often and are represented by capital letters

• Summary: explain why your monster ended up look like that.

• OUT: how can you use the information you learned this week to determine if your mom or dad has more dominate traits.
