BIOD 210 EXAM PREP UPDATED 2026
PRACTICE QUESTIONS AND VERIFIED
ANSWERS ALREADY GRADED A+
◉Karyotype . Answer: A display of the chromosome pairs of a cell
arranged by size and shape.
◉T or F: In some cases, a genetic disorder only manifests subtle
outward phenotypes or may appear in an individual as they age. .
Answer: True
◉BRCA1 gene mutation . Answer: Genetic mutation increasing breast
cancer risk.People who inherit a BRCA1 mutation have more than an
80% risk of developing breast or ovarian cancer in their lifetime.
◉Sickle Cell Anemia . Answer: The mutant β-globulin causes the
hemoglobin within red blood cells to distort when the oxygen in the
blood is low
◉Gregor Johann Mendel . Answer: Famous for experimenting with pea
plants to observe the occurrence of inherited traits. He eventually
became known as the father of genetics.
, ◉Why are pea plants are good for genetics studies? . Answer: + very
easy to grow and breed
+ self-fertilizing
+ very easy to cross-breed
◉How in-depth was Mendel's experiment? . Answer: Bred, grew, and
recorded the traits of over 30,000 individual plants.
◉Traits . Answer: distinguishing characteristics of an organism
◉Phenotypes . Answer: Physical expressions of genetic trait
◉Mono-Hybrid Cross . Answer: Occurs when two pure individual
parental strains are mated that contrast ONLY in the trait that is being
observed.
◉Mendel's Three Postulates . Answer: I. "Genetic characters are
controlled by unit factors existing in pairs in individual organisms"_
II. "When two unlike unit factors responsible for a single characteristic
are present in a single individual, one unit factor is said to be dominant
to the other, which is said to be recessive"
