What each of the human chromosomes look like

Karyotype: A photomicrograph of chromosomes arranged in pairs

In other words…
• Chromosomes are digitally arranged so that they are matched with their homologue or “partner” chromosome.
• Homologue chromosomes are the same size , shape , and carry the same genes , and one is inherited from each parent .
• They are numbered according to size .

Sex determination with karyotype
• This karyotype has 23 exact pairs, which means the person is female.
• Note that #23 chromosomes are both X.

Normal human male
• Note that #23 chromosomes are X and Y.

Is this person female or male?

Trisomy 21
• Abnormality shown in karyotype
• Note that there are three copies of #21 chromosome.
• This person has Down
Syndrome.

Society

Correlation between mother’s age and Trisomy 21 incidence

• Abnormality shown in karyotype
• Note this person only has 1 copy of the X chromosome.
• This female has
Turner’s syndrome.
