Genetics

• telomeres - the end of the chromosomes
• The three levels of priority in fuel metabolism are carbohydrates, lipids, and proteins
• Complete dominance - when the dominant allele completely masks the effect of the recessive allele
• Incomplete Dominance - alleles of a gene are partially expressed, often resulting in a different or mix of phenotypes
• stem cells - non-specialized cells that can become a specialized cell
• cell differentiation determines fate of cell
• tetrad - a group or set of four.
• karyotype - the number and visual appearance of the chromosomes in the cell nuclei of an organism or species.
