    D. trait
  8. Out of the 23 pairs of human chromosomes in our body cells, how many pairs determine whether a person in male or female.

    D. one

    b. boy
    a. girl

    A girl will have XX chromosomes.
  11. Persons with an X and a Y chromosome are______.

    a. male
    b. females
    a. male

    In males, one chromosome is X and the other chromosome is Y.
  12. All female eggs carry ____ chromosome.

  14. The male sex cell is called _________.

    C. the sperm
  15. The male sex cell, the sperm, carry ______ chromosome.

    D. an X or a Y 
  16. Who determines the gender of the offspring.

    a. the male
    b. the female
    a. the male
  17.  A _________ is a chart or family tree geneticists use to trace the inheritance of traits passsed down by family members.

    C. pedigree
  18. A ________ is an abnormal condition that a person inherits through the genes or chromosomes.

    C. genetic disorder
  19. A mutation is a ____________.

    D. change
  20. Genetic disorders are caused by ____________ in a person's DNA.

    C. mutations
  21. Which of the following IS NOT a method that people have used to develop organisms with desirable traits.

    A. evolution

    People do not have control over evolution.
  22. ______________ is the process of selecting a few organisms with desired traits to serve as parents of the next generation.

    A. selective breeding
  23. The selective breeding process that involves crossing two individuals that have identical or similar sets of alleles is called _________.

    D. inbreeding
  24. Inbreeding always produces desirable traits.


    Although inbreeding may produce desiralbe traits, there is a risk that an organism may also inherit alleles that lead to genetic disorders.
  25. Hybridization is a cloning technique.


    Hybridization is a SELECTIVE BREEDING technique.
  26. The process by which breeders cross two genetically different organisms to produce an offspring that possesses the best traits of both parents.

    A. hybridization
  27. The technique in which an organism is created that is genetically identical to the organism from which it was produced.

    D. cloning
  28. This technique is also called genetic splicing.

    C. genetic engineering
  29. The process by which a DNA molecule is cut open and a gene from another organism is spliced into it to produce an organisim with desired traits.

    C. genetic engineering
  30. The first successful genetic engineering, was used to treat 

    D. diabetes

    A human gene was spliced with a bacterium to quickly produce insulin.
  31. Identical twins have the same DNA.

  32. Since no two people, except identical twins, have the same DNA, it is possible to use DNA fingerprinting to _____________.

    A. help solve crimes.
  33. A ___________ is the entire DNA in one cell of an organism.
