Study Notes
Cell Genetics
- A cell that contains two sets of chromosomes is called diploid.
- A cell that contains one set of chromosomes is called haploid.
- The fusion of a sperm and an egg cell results in a zygote.
- A human zygote contains 46 chromosomes.
- A human cell contains 23 pairs of chromosomes.
- The two copies of a chromosome that make up a pair are called homologous chromosomes.
- The two identical copies of a chromosome that are held together by a centromere are called sister chromatids.
- The structure that connects sister chromatids is the centromere.
- Chromosomes that are not involved in determining an individual's sex are called autosomes.
- Cells of the body that are not involved in reproduction are called somatic cells.
Cell Cycle and Division
- DNA replication occurs during the S phase of the cell cycle.
- The process by which homologous chromosomes exchange genetic material is called crossing over.
- Meiosis is the type of cell division that results in the formation of gametes.
- The loss of one or more chromosomes during cell division is called aneuploidy.
- Sexual reproduction involves the fusion of gametes from two parents.
Genetics and Evolution
- The random distribution of homologous chromosomes during meiosis is called independent assortment.
- Directional selection is the type of selection that favors extreme phenotypes and reduces genetic diversity.
- Microevolution is the change in the frequency of alleles in a population over time.
- Natural selection is the process by which individuals with advantageous traits are more likely to survive and reproduce.
- Population genetics is the study of the distribution and frequency of alleles in populations.
- Crossing over is the process by which homologous chromosomes exchange genetic material.
