KaryotypesKaryotypes
• Humans have 46 chromosomes in normal body cells
• Karyotypes show chromosomes in pairs lined up from biggest to smallest
• Having the wrong number of chromosomes gives you a
• Down’s syndrome = trisomy 21 =
• Down’s syndrome is caused by
diseaseAn extra 21st chromosome
nondisjunction
KaryotypesKaryotypes
• Nondisjunction = chromosomes don’t separate when the egg or sperm is made, so there is the wrong number of chromosomes
Triple X Syndrome (notes)Triple X Syndrome (notes)
• Triple X Syndrome = females with an extra X chromosome (XXX)
Think: Karyotypes
• What chromosomal combinations produces a male? Female?
• How many chromosomes are found in a typical human cell?
• Down’s syndrome patients have ___x copies of chromosomes 21.
A man wants to investigate plant height using pea plants: His pea plants come in only 3 heights. He has tall plants (TT), short plant (tt) and medium plants (Tt). What are the probable genotypes and phenotypes?
