BIOD 210 FINAL EXAM QUESTIONS AND
ANSWERS 100% CORRECT
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
in ___________________________, a single phenotype is affected by more than a
single gene - ANSWER-gene interaction
In the case of a _________________, the mutation in a gene results in a total loss of
the gene's function - ANSWER-null allele
The phenomenon of an intermediate phenotype of the parental strains is known as
________________
give an example of this - ANSWER-incomplete or partial dominance
a white flower + red flower creating pink flower offspring
A __________ cross occurs when two pure individual parental strains are mated that
contrast ONLY in the trait that is being observed - ANSWER-monohybrid
In genetics, _______ refers to the original parental generation - ANSWER-P1
The first set of offspring from the parents are called the ___ generation, which stands
for ______________. - ANSWER-F1 , first filial generation
