  • Differences in the genetic makeup among individuals of the same species.
    Genetic variation
  • The passing of traits from parents to offspring.
    Heredity
  • A segment of DNA that codes for a specific trait or protein.
    Gene
  • A cell or organism with two sets of chromosomes (2n).
    Diploid
  • A genetic change that improves an organism's chances of survival or reproduction.
    Beneficial mutation
  • A structure in the cell nucleus that contains DNA and genes.
    Chromosome
  • A large molecule that performs various functions in the body and is coded for by genes.
    Protein
  • Pairs of chromosomes that carry genes for the same traits.
    Homologous chromosomes
  • The ability of an organism to regrow its body parts.
    Regeneration
  • The genetic material that carries instructions for an organism's development and functioning.
    DNA
  • A genetic change that decreases an organism's chances of survival or reproduction.
    Harmful mutation
  • A genetic change that does not significantly affect an organism's survival or reproduction.
    Neutral mutation
  • A cell produced by the division of a parent cell.
    Daughter cell
  • A type of reproduction involving two parents and the fusion of gametes.
    Sexual reproduction
  • A cell or organism with a single set of chromosomes (n).
    Haploid
  • A type of reproduction involving only one parent, resulting in genetically identical offspring.
    Asexual reproduction
  • The process of cell division that results in two identical daughter cells.
    Mitosis
  • A form of asexual reproduction where a new organism grows from a part of the parent organism.
    Budding
  • A reproductive cell (egg or sperm) that contains half the genetic information of the parent.
    Gamete
  • The exchange of genetic material between homologous chromosomes during meiosis.
    Crossing over
  • The cell formed when two gametes fuse during fertilization.
    Zygote
  • A form of asexual reproduction in single-celled organisms where the cell divides into two identical cells.
    Binary fission
  • A change in the DNA sequence of a gene or chromosome.
    Mutation
  • The process of cell division that produces gametes with half the number of chromosomes.
    Meiosis
  • A characteristic or feature of an organism.
    Trait
