Proverb of the Day “There’s no better way to overpower a trickle of doubt than with a flood of naked truth.” – House of Cards

Karyotypes The study of inheritance patterns in humans Oculocutaneous albinism

What each of the human chromosomes look like

Karyotype: A photomicrograph of chromosomes arranged according to a standard classification

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.

Photos of Down Syndrome patients from the National Down Syndrome Society

Correlation between mother ’ s age and Trisomy 21 incidence

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

Turner’s Syndrome

XXY Male (Extra X)

How are DNA samples obtained for karyotypes?

Amniocentesis: obtaining amniotic fluid which has cells from the fetus
