BIOD 210 Genetics Final Exam 2027 Question and Answer |
Grade A+ | Complete Verified Guide
Question 1.
Describe Sickle Cell Anemia
Correct 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.
Question 2.
Why did Mendel use a pea plant for his studies?
Correct Answer: - Easy to grow and breed - Self-fertilizing - Easy to
cross-breed
Question 3.
A __________ cross occurs when two pure individual parental strains are mated that
contrast ONLY in the trait that is being observed
Correct Answer: monohybrid
Question 4.
In genetics, _______ refers to the original parental generation
Correct Answer: P1
Question 5.
The first set of offspring from the parents are called the ___ generation, which stands for
______________.
Correct Answer: F1 , first filial generation
Question 6.
The term _____________ is used to describe the physical manifestation of any trait
Correct Answer: phenotype
