Mendel's Basic Laws of Heredity The rules to genes and how they work
Punnet Square A chart that shows all of the possible combinations of alleles that can result from a genetic cross; used to predict the possibility of a particular offspring
Dominant Allele When present more than once in a gene, the trait it codes will be expressed in the offspring
Recessive Allele Only expressed when there are two copies of it in a gene pair; if dominant allele is present, it will be "covered up" and not expressed
Phenotype The way something looks and how the trait is expressed using a ratio
Genotype The actual combination of genes using a ratio
Homozygous The same allele
Monohybrid A Punnet square which follows the inheritance of one trait
Heterozygous A dominant and a recessive gene in a pair
Mitosis The process where a cell divides, giving rise to two identical daughter cells; contains the same number of chromosomes
Meiosis The process only occurs in sex cells(sperm and egg)by which the number of chromosomes is reduced by half
Chromosomes A structure within the nucleus that is made of DNA and protein
Deoxyribo Nucleic Acid (DNA) Genetic material that carries information about an organism that is passed from parent to offspring; found in the nucleus of a cell
Chromatid One type of rod of the chromosome
Genes Segments of DNA located on chromosomes; codes are for a particular protein or function, like eye or hair color
