Karyotyping is typically done by isolating ________ from a person, staining
them, and taking pictures under a microscope - 🧠 ANSWER ✔✔white blood
cells
Describe Sickle Cell Anemia - 🧠 ANSWER ✔✔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.
Why did Mendel use a pea plant for his studies? - 🧠 ANSWER ✔✔- Easy to
grow and breed
- Self-fertilizing
- Easy to cross-breed
A __________ cross occurs when two pure individual parental strains are
mated that contrast ONLY in the trait that is being observed - 🧠 ANSWER
✔✔monohybrid
