Breaking Down Common Biology Semester 2 Exam Review
Answers
Let’s explore some typical questions and answers you might encounter, along with
explanations to deepen your understanding.
Genetics: Understanding Mendelian Inheritance
**Question:** In pea plants, the allele for tall (T) is dominant over short (t). What is the
genotype ratio of the offspring from a cross between two heterozygous tall plants?
**Answer:** The genotype ratio is 1 TT : 2 Tt : 1 tt.
**Explanation:** When crossing two heterozygous (Tt) individuals, use a Punnett square to
predict offspring genotypes:
TT (homozygous dominant)
Tt (heterozygous)
tt (homozygous recessive)
The ratio reflects the probability of each genotype appearing in the offspring.
Evolution: Natural Selection Mechanisms
**Question:** How does natural selection lead to evolution?
**Answer:** Natural selection leads to evolution by favoring individuals with
advantageous traits that increase their chances of survival and reproduction. Over time,
these traits become more common in the population.
**Explanation:** This process causes genetic changes within populations, driving
evolutionary adaptations to the environment.
Human Anatomy: The Circulatory System
**Question:** Describe the flow of blood through the heart starting from the body.
**Answer:** Blood from the body enters the right atrium via the superior and inferior vena
cava, flows into the right ventricle, and is pumped to the lungs through the pulmonary
artery. Oxygenated blood returns to the left atrium via pulmonary veins, moves to the left
ventricle, and is then pumped out to the body through the aorta.
**Explanation:** Understanding this flow is vital for answering questions about heart
function and blood circulation.
