Across
  1. 4. passing of traits from parents to offspring
  2. 6. used to determine the genotype of an organism with a dominant phenotype
  3. 9. the genetic makeup of an organism
  4. 10. basic unit of inheritance
  5. 11. a genetically determined characteristic
  6. 13. two copies of a mutated gene are needed to cause the trait/disorder
  7. 15. two different copies of an allele
  8. 17. chart that traces ancestry
  9. 19. allele expressed in heterozygous or homozygous pairs
  10. 20. two identical copies of an allele
  11. 21. animals share a descendant
  12. 22. dominant alleles completely blocks the recessive allele
  13. 23. only one copy of a mutated gene is needed to cause the trait/disorder
Down
  1. 1. law that says a pair of alleles segregate during meiosis
  2. 2. first generation of individuals in a genetic cross
  3. 3. pair of chromosomes that have similar gene content, size, and shape
  4. 5. cross where both parents are heterozygous for a single trait
  5. 7. law that says genes do not influence each other with regard to the sorting of alleles into gametes
  6. 8. offspring of the P generation
  7. 12. different forms of a specific gene
  8. 14. physical makeup of an organism
  9. 16. allele expressed only when homozygous
  10. 18. cross where both parents are heterozygous for two different traits
