  1. 2. Phenotypes of the heterozygote and the homozygote dominant are the same; _________ Dominance
  2. 3. Each pair of alleles (on either homologous chromosomes or sister chromatids) seperate completely independently of one another during Anaphase I & II
  3. 8. Observable characteristics (visible or behavior) of an individual resulting from their genotype
  4. 11. One gene alters the phenotypic expression of another gene
  5. 12. Phenotype is a mix of both parent's phenotypes; _________ Dominance
  6. 13. Environment favors one phenotype over another, improving that organism's chances of survival; _________ Selection
  7. 14. Exchange of alleles between homologous chromosomes during Prophase I
  8. 15. Genetic makeup of an individual
Down
  1. 1. Diploid cell has two different alleles for a specific gene; Ex: Aa
  2. 4. Phenotype is influenced by genes located on the X chromosome
  3. 5. Chromosomes fail to completely seperate during Meiosis which results in gametes with abnormal numbers of chromosomes
  4. 6. Diploid cell has two identical alleles for a specific gene; Ex: BB or bb
  5. 7. Phenotype of the heterozygote expresses both distinct parental traits; ____-Dominance
  6. 9. Method of determining the unknown genotype of an individual by crossing them with a known Homozygous recessive individual
  7. 10. Genes located near each other on the same chromosome are unlikely to cross over so they are often inherited together
