Gene Regulation Mechanisms
Students explore genetics. They discuss how chromosomes and/or genes are regulated during the life of an organism. In a lab setting, students compare and contrast the genomic regulation of prokaryotic and eukaryotic cells using manipulatives.

Mutations - When Good DNA Goes Bad
What do Ninja Turtles and Spiderman have in common? Hollywood has displayed them as the results of mutation. Biology whizzes take a look at real mutations in fruit flies, and then learn the difference between gene mutation and chromosomal mutation.

Genetics 101 Part 3: Where do Your Genes Come From?
These aren't the type of jeans you can buy at a local store! Help your class understand what determines if you're a girl or a boy. Show this cartoon representation of how a male and a female's chromosomes shuffle, divide, and recombine to create a baby.

Genetics 101 Part 2: What are SNPs?
If humans share over 99% of the same chromosomes, how are we different? There are 10 million SNPs in the human genome, accounting for most of our genetic differences. Watch this short clip to introduce your learners to SNPs, or single nucleotide polymorphisms.

Begin looking at reproduction by contrasting sexual reproduction with asexual reproduction. Sexual reproduction gives us genetic variation as meiosis creates brand new chromosomes through cross over. Male and female anatomy is covered, as well as menstruation and fertilization.

Facts of Life - Gender Determination
Why do Y chromosomes result in boys? This video explains that the default human being is female, but a sex-determining region, or SRY, on the Y chromosome is the single gene that tells the cells to produce a male before disappearing. It directs the embryo to develop male organs, produce sperm cells, and perform basic cell housekeeping.

Mitosis, Meiosis and Sexual Reproduction
Sal from the Khan Academy draws an example of sexual reproduction and the chromosomes that come together from each gamete. Mitosis is also explained about halfway through the video, eventually showing differentiation and meiosis. Give your learners a cyclical view of how mitosis and meiosis work to create a new person!
