  1. Chapter 5 Heredity

  2. The passing of genetic traits from parents to offspring Heredity

  3. The trait observed in the first generation when parents that have different traits are bred; trait that shows in the phenotype Dominant Trait

  4. A trait that reappears in the second generation after disappearing in the first generation when parents with different traits are bred; only shows when TWO recessive alleles are present Recessive Trait

  5. One set of instructions for an inherited trait Gene

  6. One of the alternative forms of a gene that governs a characteristic, such as hair color Allele

  7. An organism’s appearance or other detectable characteristic Phenotype

  8. The entire genetic makeup of an organism; also the combination of genes for one or more specific traits Genotype

  9. The likelihood that a possible future event will occur in any given instance of the event Probability

  10. Chromosomes that have the same sequence of genes and the same structure Homologous Chromosomes

  11. A process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells Meiosis

  12. One of the pair of chromosomes that determine the sex of an individualXX = FemaleXY = Male Sex Chromosomes

  13. A diagram that shows the occurrence of a genetic trait in several generations of a family Pedigree
