  3. What is the name of the chromosomes that are not sexchromosomes? And how many do we have? • Autosomal • We have 22 pair

  4. Humans have 3 alleles for blood type, A, B and O, which of these 2 alleles are codominant and which one is recessive?

  5. A and B are codominant • O is recessive

  6. Pedigree • A chart that is used to analyze the pattern of inheritance Non shaded indicates the trait is not express = male A shaded shape indicates a certain trait is expressed = female

  7. Chromosomal disorders • Nondisjunction- when homologous chromosomes fail to separate during meiosis.

  8. Nondisjuntion disorders • Trisomy – three bodies (three chromosomes • instead of 2. • -The most common is Down Syndrome Turner’s syndrome (X)- Female sex organs do not develop properly Klinefelter’s syndrome- (XXY) in males, prevents individuals from reproducing
