Development and Mendel

2. name given to the developing organism during the early stages of development
5. the genetic makeup of an organism
6. the third and middle layer of cells that forms between the endo and ectoderm layers
8. the inner layer of cells in the gastrula
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
13. The passing of genes from parents to offspring
14. the physical trait that an organism develops and shows
17. the outer layer of cells in the gastrula
18. the rearranging of cells to create the primitive gastrointestinal system (primitive gut)
21. when the alleles of a certain trait are the same
23. when more than 2 alleles affect a genotype
24. when both alleles contributed to the phenotype of a heterozygous individual produce a trait that is not exactly like either parent
25. when the alleles of a certain trait are different

1. Where the embryo develops with the female body (womb)
3. the trait that is always hidden in a hybrid organism
4. an organism that contains contrasting traits
7. a section of DNA that encodes a particular function/makes a particular protein
9. the changing of unspecialized embryonic cells into the specialized cells, tissues, and organs necessary for the organism
10. the complex series of changes that form a zygote into a new organism
12. different forms of a gene controlling a particular trait
15. a type of characteristic you show like bbeing tall or short
16. two dominant alleles are expressed at the same time
19. stem cells that are able to differentiate into all cell types of the adult organism
20. the trait that always shows in a hybrid organism
22. the branch of biology that studies how hereditary information is passed on from parents to offspring
