Organ Organ System Organism Organelles Population Genotype – the genetic makeup of an organism Phenotype – the expression of a trait Dominant traits tend to mask recessive traits. A recessive trait will only be expressed in a dominant trait is not present. Heterozygous – the presence of two different genes. Example: Bb – this person possesses one brown-eyed gene and one blue-eyed gene. Homozygous – the presence of the same two genes. Ex: BB or bb – these people possess two of the same gene. Natural Occurrence is the process by which the traits of organisms change over generations as a result of environmental factors. Examples: Bacterial resistance to antibiotics, Peppered Moths. Selective Breeding occurs when humans, not nature, select which plants or animals will reproduce based on desired traits. Examples including breeding racehorses for speed, vegetables to repel bugs, etc. Pathogens Communicable Non-communicable Virus, Bacteria, Fungus, Parasites, Prions (theory) Antibodies Antibiotics Vaccine
