  1. Explain how DNA genes and chromosomes are related
    DNA is the basic building block of genes specific segments of DNA form a gene and many genes form and chromosome
  2. What is the Human Genome Project?
    An international effort to map all genes contained in the 46 human chromosomes.
  3. Autosomal recessive
    • A child must receive a copy of autosomal recessive gene from BOTH parents, no sex difference
    • 25% chance each pregnancy
  4. Autosomal dominant
    • Child may receive a copy of autosomal dominant gene from either parent, no sex difference
    • 50% chance each pregnancy
  5. X-linked recessive
    • Females are carries, child receives abnormal gene from mother
    • Males are affected because they do not have a compensating normal X chromosome
    • Affected fathers will pass on abnormal genes to their daughters who become carries but not to their son.
