white blood cells Karyotyping is typically done by isolating ________ from a person,
staining them, and taking pictures under a microscope
People who inherit a mutant copy of the β-globulin protein from both parents have sickle-cell
anemia. The mutant β-globulin causes the hemoglobin within red blood cells to distort when the
oxygen in the blood is low, and in fact, deforms the cell shape so much that the distorted cells
break very easily. In turn, the loss of the broken cells lowers the total number of red blood cells,
resulting in anemia
In addition, the odd shape of the red blood cells actually causes blockages in small blood vessels,
which causes pain and damage to the brain, heart, muscles, and kidneys. The condition is
especially exacerbated under atmospheric conditions where oxygen is lower, so people with
sickle-cell anemia can become extremely sick at high altitudes. Describe Sickle Cell

- Self-fertilizing
