Across
  1. 3. Father of Genetics
  2. 6. nucleotide that pairs with cytosine
  3. 7. "middle" part of the chromosome that kinda pinches in
  4. 10. somatic cells have 2 sets of chromosomes & are considered to be ______________
  5. 11. heterozygous individuals for the sickle cell allele have resistance to this disease
  6. 13. the 3 mRNA nucleotides that represent 1 amino acid
  7. 15. sugar found in RNA
  8. 16. nucleotide that substitutes for thymine
  9. 17. DNA replication creates ____________________________
  10. 20. genetic situation where the heterozygous phenotype is in between the 2 homozygous phenotypes
  11. 21. crossing over occurs between the 2 ______________ chromatids of the tetrad (aka the non-sister chromatids)
  12. 24. process of reading mRNA to make proteins
  13. 26. the physical appearance based on gene expression
  14. 28. allele that is hidden
  15. 29. another name for homologous chromosomes
  16. 31. crossing over creates _______________________ chromsomes
  17. 32. the organism that transmits the disease heterozygous sickle cell individuals are resistant to
  18. 34. meiosis creates _________________ cells because they only have half of the chromosomes as the original cell
  19. 35. this stage is the same as mitosis because it separates sister chromatids
Down
  1. 1. where hemoglobin is normally found in our bodies
  2. 2. sugar found in DNA
  3. 4. gene that is mutated and causes sickle cell disease
  4. 5. when independent assortment occurs
  5. 8. process of reading DNA to make RNA
  6. 9. structure of DNA
  7. 12. organelle that makes proteins
  8. 14. end products of meiosis (aka sperm and egg)
  9. 18. the predicted phenotypic ratio when 2 heterozygous parents have offspring
  10. 19. meiosis creates this many unique cells
  11. 22. when crossing over takes place
  12. 23. this inheritance type is seen with skin pigmentation
  13. 25. nucleotide that pairs with uracil
  14. 27. the genetic make-up of an organism
  15. 30. tetrads are also called _____________ chromsomes
  16. 33. crossing over & independent assortment increase _________ which allows evolution to occur
