Independent assortment of traits and chromosomes demonstrated by dihybrid crosses with two traits.
Morgan's experiments with fruit flies showed linkage between two genes/traits. Dihybrid crosses with two traits show genetic recombination and genetic distances.
Sturtevant's work with multiple traits mapped out genes on chromosomes based on recombination frequencies. Genetic maps allowed biologists to predict frequency of double recombination.
X and Y chromosomes determine gender. In fruit flies, certain physical traits such as eye color lie on the X chromosome and are linked to the sex of the fly.
Eukaryotes and prokaryotes vary in DNA replication due to differences in chromosome structure and genome sizes.
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.
Characteristics of chromosomes. Drawing of mitosis and the changes and segregation of chromosomes. Definition: Mitosis, chromosome, chromatid, and centrosome. Great video of mitosis.
Autosomes versus sex chromosomes. Morgan's experiment which discovered sex-linkage. Carriers and inheritance patterns.
Details about genes, chromosomes, and the human genome.
Clarification of genes, alleles, traits, genotype, phenotype, and dominance.
Recombination between two linked genes used to construct genetic maps.
Comparison between chromosomal segregation during mitosis, meiosis I and meiosis II and DNA recombination.
Use family pedigree to predict the mode of inheritance. Predict gene arrangement on the chromosomes based on linkage.
Characteristics of linked genes and calculation of recombination frequencies.
Table comparing cell division through mitosis and meiosis-process and cellular components involved.
Conceptual questions on the Chromosomal Theory of Inheritance, sexual reproduction, and chromosomal recombination.
Two examples of human pedigrees used to predict the mode of inheritance. Recombination is taken into consideration when calculating probability of inheritance.
