Presentation Transcript

Karyotype
Karyotype

  • arrangement of chromosomes from one body cell


Sex chromosomes
Sex Chromosomes

  • Determine the sex of the individual

  • In humans: X and Y chromosomes

  • X chromosome larger

    than Y chromosome




Atypical meiosis
Atypical Meiosis

  • Chromosomes do not separate properly during meiosis

  • Results in gametes with too little or too much genetic information


Down syndrome
Down Syndrome

  • Zygote contained 47 chromosomes

  • 3 copies of chromosome 21


Sex chromosome disorders
Sex Chromosome Disorders

  • Klinefelter syndrome: males born with 2 X chromosomes
