Carbohydrate an energy-rich organic compound that is made of the elements carbon, hydrogen, and oxygen Protein large organic molecule made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur Lipid an energy-rich organic compound, such as fat, oil, or wax, that is made of carbon, hydrogen, and oxygen Asexual a reproductive process that involves only one parent Reproduction and produces offspring that are identical to the parent Sexual a reproductive process that involves two parents that Reproduction combine their genetic material that produces an offspring that differs from both parents Mitosis the second stage of the cell cycle during which the cell’s nucleus divides into two new nuclei and one set of DNA is distributed into each daughter cell Round 2 Round 3 Meiosis the process that occurs in the formation of sex cells (sperm and egg) by which the number of chromosomes is reduced by half DNA the genetic material that carries information about an organism and is passed from parent to offspring Chromosome a threadlike structure within a cell’s nucleus that contains DNA Gene a sequence of DNA that determines a trait and is passed from parent to offspring Alleles the different forms of a gene Mutation any change in the DNA of a gene or a chromosome Heredity the passing of traits from parents to offspring Dominant an allele whose trait always shows up in the organism when the allele is present Recessive an allele that is hidden whenever the dominant allele is present Pedigree a chart that shows the presence or absence of a trait according to the relationships within a family across several generations Homozygous having two identical alleles for a particular gene Heterozygous having two different alleles for a particular gene Evolution change over time; the process by which modern organisms have descended from ancient organisms Natural the process by which organisms that are best adapted Selection to their environment are most likely to survive and reproduce Artificial the intentional reproduction of individuals in a Selection population that have desirable traits Fitness the ability of an organism or population to survive and pass its genes to its offspring Adaptation an inherited behavior or physical characteristic that helps an organism survive and reproduce in its environment Winners:
