The discovery of chromosomes and brief overview of meiosis in the context of Mendel's work. Chromosome theory of inheritance-traits are carried on chromosomes that segregate when gametes form.
Brief overview of mitosis and meiosis and the segregation of chromosomes in the context of Mendel's theory.
Two traits that are on the same chromosome may not segregate independently. Genetic linkage reconciles Mendel's theory and the Chromosomal Theory of Inheritance.
Explanation of steps and characteristics of meiosis. Definition: Meiosis I and II, chiasma
Fertilization and the combination of chromosomes from the egg and sperm. Chromosomes as the carriers of genetic particles.
Inaccurate segregation of chromosomes. Trisomy and monosomy as result of defects in meiosis.
Detailed description of steps of meiosis I and meiosis II and comparison to mitosis. Should use in conjunction with textbook diagrams.
Explanation of homologous recombination that occurs during the prophase of meiosis I. Generation of new chromatids and chromosomes during recombination give rise to diversity.
How errors in meiosis occur, and how these errors are manifested in the final organism.
Lineages for the sperm and egg. Cell divisions and differentiations during the formation process.
Hormones as long-range inducers for gametogenesis. Produced in the brain, travel through the blood stream to the ovaries and testes. Balance of various stimulatory and inhibitory hormones and feedback loop induce gametogenesis.
Comparison between chromosomal segregation during mitosis, meiosis I and meiosis II and DNA recombination.
Transcription and translation of a given gene and DNA mutations that affect the protein product.
Inheritance of traits based on segregation of chromosomes.
Table comparing cell division through mitosis and meiosis-process and cellular components involved.
