Heredity the passing on of traits or characteristics from a parent to its offspring
Trait A quality that belongs to a certain person.
Purebred when two animals with the same traits sexually reproduce, the offspring is considered to be Purebred.
Hybrid when two animals sexually reproduce (and they both have different traits), the offspring is considered to be a hybrid.
Offspring the product of the reproductive process of an animal, or A child.
Gene DNA, heredity
Alleles a certain gene belonging to an organism
Dominant a gene that is shown physically in an organism
Recessive a gene that is hidden and cannot be shown on an organism
Phenotype characteristics of a certain organism
Genotype the genetic makeup of an organism
Homozygous when an organism has two of the same allele/gene.
Codominance when a pair of genes is neither dominant nor recessive
Meiosis the cell division to create sex cells
Haploid Cells A cell that is the result of meiosis and has half the number of chromosomes as the original cell.
Diploid Cells A cell that is the result of mitosis and has the same number of chromosomes as the original cell.
Mutations a change in a gene/chromosome

Genetic Engineering the modification of characteristics in a organism
Gene Therapy changing defective genes and replacing them with normal ones to correct gene disorders
Respiration where cells obtain energy from glucose
Fermentation the chemical breakdown of a substance or bacteria
Cell Cycle events in a cell as it grows
Chromosomes a structure of nucleic acids and proteins that carry genetic information
Animal Cell a eukaryotic cell containing a membrane surrounding the nucleus and the cell itself
Plant Cell a eukaryotic cell containing a membrane and cell wall around the cell itself; it also has several different organelles than the animal cell.
Thymine one of the four nucleobases in DNA
Adinine a Nucleobase with a variety of roles like cellular respiration.
Heterozygous when an organism has two different alleles.
