1. Traits and Heredity
:: Important Definitions ::
Trait: characteristic or attribute.
Heredity:The passing of characteristics genetically from one generation to the next.

2. Genes, DNA, and Chromosomes
:: Important Definitions ::
Genes: Genes are a part of DNA that determines a particular trait.
DNA: the genetic material that carries coded information about an organism.
Chromosomes: an organized structure of DNA located in the nucleus. (The DNA gets coiled up/shorter/thicker).
:: Internet Resources ::

Brainpop: DNA: The video on DNA will help show what it is. If you have a Brainpop account (our school has them), you can click some of the other resources.

3. Punnett Squares
:: Important Definitions ::
Homozygous: Two of the same alleles in a genotype (either both dominant or both recessive).
Heterozygous: Two different alleles in a genotype. (One dominant and one recessive).
Dominant allele: If you have at least one dominant allele, the dominant trait will show.
Recessive allele: If there are two recessive alleles, you will see the recessive trait.
Genotype: Two allele combination.
Phenotype: What you see on the outside.

4. Mitosis
:: Important Concepts ::
Interphase: the phase when the cell is "just doing its job."
Mitosis is the process of splitting one nucleus into two new nuclei.
- Mitosis has four stages that we talk about in 7th grade science:
Prophase, Metaphase, Anaphase, Telophase.
Cytokinesis: The process of having two new cells where the cytoplasm finally splits.

5. Meiosis
:: Important Concepts ::
Meiosis is similar to Mitosis, but has very important differences.
Meiosis is split into two stages. It goes through Prophase I, Metaphase I, Anaphase I, Telophase I, and then Prophase II, Metaphase II, Anaphase II, and Telophase II.
