- 3. where a piece of a colony or organism is broken off and replaced through mitosis
- 4. this is an example in humas of multiple alleles

- 10. the actual of genes in an organism (i.e., BB, Bb or bb)
- 11. there are _______ pairs of chromosomes in a human
- 12. form of cell division where haploid cells like eggs and sperm are formed
- 13. haploid cells used in reproduction
- 15. two alleles are different (i.e., Dd)
- 17. gene that is hidden when with a dominant gene
- 18. fertilization of two gametes
Down
- 1. the two factors influencing an individual’s characteristics are their genetics and their _______
- 2. process where eggs are formed
- 5. phase of the cell cycle where the cell grows and carries on its normal activities
- 6. this is used to tell if a dominant trait is homozygous or heterozygous
- 7. Gregor Mendel developed his principles of genetics while studying these
- 9. a cross that deals with only one trait
- 14. the physical expression of a gene (i.e., height or color)
- 16. these are long strings of DNA that exist when a cell is dividing
