  1. 6th Grade Science

  2. When pollen is transported to a different flower ___________ occurs.

  3. Cross-pollination

  4. The of trait that appears in the hybrid generation is the _____________trait.

  5. Dominant

  6. A self pollinated organism that shows the same form of a trait in all its offspring for several generations of self-pollination is said to be____________.

  7. Purebred

  8. What are inherited traits?

  9. Characteristics that are passed from parents to offspring.

  10. The passing of inherited traits from one generation to the next is called___________.

  11. Heredity

  12. Humans do not inherit traits, they inherit ___________for traits.

  13. A capital letter stands for the ________________ factors.

  14. Dominant

  15. Factors

  16. Parents pass inherited traits to their offspring during_______________.

  17. Reproduction

  18. What is a recessive trait?

  19. A recessive trait is the form of a trait hidden or masked in the hybrid generation.

  20. Genes that a carried only on the x chromosome are called_________________.

  27. ___________________is the process in which scientists can take the genes of one organism and attach them to another.

  28. Gene-splicing

  29. What is a clone?

  30. A living thing that receives all its DNA from just one parent.

  31. ________________is the process of crossing plants and animals to produce offspring with certain desirable traits.

  32. Selective Breeding

  33. ___________________ is a way of changing the DNA sequence that makes up a gene so that the gene will produce a particular trait.

  34. Genetic Engineering
