Across
  1. 2. name given to the developing organism during the early stages of development
  2. 5. the genetic makeup of an organism
  3. 6. the third and middle layer of cells that forms between the endo and ectoderm layers
  4. 8. the inner layer of cells in the gastrula
  5. 11. developmental organ where nutrients and oxygen diffuse from a mothers blood into the embryo’s blood, and waste from the embryo is diffused out
  6. 13. The passing of genes from parents to offspring
  7. 14. the physical trait that an organism develops and shows
  8. 17. the outer layer of cells in the gastrula
  9. 18. the rearranging of cells to create the primitive gastrointestinal system (primitive gut)
  10. 21. when the alleles of a certain trait are the same
  11. 23. when more than 2 alleles affect a genotype
  12. 24. when both alleles contributed to the phenotype of a heterozygous individual produce a trait that is not exactly like either parent
  13. 25. when the alleles of a certain trait are different
Down
  1. 1. Where the embryo develops with the female body (womb)
  2. 3. the trait that is always hidden in a hybrid organism
  3. 4. an organism that contains contrasting traits
  4. 7. a section of DNA that encodes a particular function/makes a particular protein
  5. 9. the changing of unspecialized embryonic cells into the specialized cells, tissues, and organs necessary for the organism
  6. 10. the complex series of changes that form a zygote into a new organism
  7. 12. different forms of a gene controlling a particular trait
  8. 15. a type of characteristic you show like bbeing tall or short
  9. 16. two dominant alleles are expressed at the same time
  10. 19. stem cells that are able to differentiate into all cell types of the adult organism
  11. 20. the trait that always shows in a hybrid organism
  12. 22. the branch of biology that studies how hereditary information is passed on from parents to offspring
