codominant trait - a single gene trait in which two different dominant gene alleles are both expressed equally such as blood type, hazel eyes, etc, DNA - Chains of genetic code contained within our genes, that determine nearly everything about us, dominant traits - Traits that always show in a person even if only one gene of the pair is inherited for the trait (you have two genes for every trait), genes - A section of a chromosome that contains the information for one trait, inheritance - The process in which genetic material is passed from parents to their offspring, recessive trait - a trait that is apparent only when two recessive genes for the same characteristic are inherited, and is hidden if paired with a dominant gene, trait - A characteristic that an organism can pass on to its offspring through its genes, chromosome - Thread-like structures in the nucleus of a cell that carry the information for the characteristics of a living organism., Gregor Mendel - The "father" of genetics; He was the first to study the patterns of traits being passed on., heterozygous - This is another term for HYBRID, homozygous - This is another term for PUREBRED., phenotype - (PHYSICAL FEATURES) This refers to the trait that is visible in the person. Does the person have freckles, or don't they; have dimples, or don't they?, punnett square - An instrument used for determining possible genetic outcomes based on biological parents' information, Mendelian Genetics - When a characteristic is controlled by one gene that has TWO possible alleles (one is dominant, one is recessive), Non-Mendelian Genetics - Pattern of inheritance whereby two alleles have a relationship that is different than the simple dominant-recessive relationship,
