Chromosomes & Cell Division
Break down cell division for your biology classes with this resource. Scholars differentiate between mitosis and meiosis, draw chromatids, and explain a few chromosomal disorders. This can likely be used as a chapter review or a note-taking guide during your lecture.

Errors of Meiosis: Chromosomal Abnormalities
After viewing these concise summaries of the common chromosome abnormalities that cause disorders, students' understanding of genetic errors will be much better. This presentation has clear diagrams to accompany the explanations. The slides have information about the genetic problems, but not many details about the disorders themselves.

Recombination and Pedigrees
Biology aces answer four questions about genetic recombination and nine questions about pedigrees. This worksheet is very focused on these two topics. Most of the pedigree questions relate to the genetic disorders, Alkaptonuria and hemophilia.

Polytene Chromosomes from Salivary Glands
Students use this laboratory procedure to outline the mechanism by which salivary glands are removed and prepared so that the polytene chromosomes may be observed.Drosophila virilis is used instead of Drosophila melanogaster because D. virilis is much larger and it is easier to dissect and remove the salivary glands from the larvae of this species.

Chromosomes, Chromatids, Chromatin, etc.
See how the strands of DNA separate and become a template for a replica to be incorporated in a new cell! The microbiology and biochemistry of the process is detailed. This lecture refers to the concepts of transcription and translation when making a protein.

Chromosomal Mutations - When Good Meiosis Goes Bad
After teaching about the process of meiosis, use this presentation to inform your biology buffs of problems that can possibly occur. Gene mutation is mentioned as a review, and then different forms of chromosome mutation are explored: nondisjunction, deletion, inversion, duplication, and translocation.

Science Lessons for Grade 11
Students explore different activities in biology, physics and chemistry. In this science lesson, students examine chromosomes using a microscope and explain their significance in sustaining life on Earth. They investigate alkanes and describe the process of 'cracking' hydrocarbons.

The Human Genotype
Six different chromosome activites introduce biology aces to heredity, chromosomal abnormalities, sex-linked traits, and the human genome. The hands-on activites are fairly simple for the teacher to prepare and will prove to be both educational and engaging.

Dragon Genetics ~ Independent Assortment and Genetic Linkage
Imagine a pair of dragons that produce offspring and determine the percentage of the hatchlings have wings and large antlers. This fantastic activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and teaches them how to use Punnett squares.

Phases of Meiosis
The general ideas behind Mitosis and Meiosis have been covered in previous videos. However, this lecture covers the minutiae of every stage in the meiotic process. The names of each phase and a description of the structure functions are detailed.

Phases of Mitosis
The lecturer starts by emphasizing that the mitotic process is a separate mechanism to cytokinesis - the cytoplasm splitting to become 2 cells. The video continues explaining the stages of mitosis in great detail. Each stage is diagrammed and the relevant structures are labeled and explained.

The Science of Inheritance
In this inheritance worksheet, students create Marshans (fictitious simple organisms) using marshmallows. Students use the chromosomes from their Marshan to fill in a data table with the genotype and phenotype. Students answer questions about their Marshan.

Biology: Genetics and Heredity
Seventh graders explore the connection between genetics and heredity by examining the cellular structure. Among the numerous activities to engage students are drawing DNA molecules, vocabulary puzzle sheets, and predicting possible offspring combinations by discovering the Punnett Squares to predict ratios for inherited traits.

An Inventory of My Traits
In this biology worksheet, students identify and describe a number of easily observable genetic traits and compare the traits they have with other students. Then they identify and describe that some traits are common while others are not and construct and read a data table and bar graph.
