ACTUAL EXAMINATION 2026 QUESTIONS
WITH SOLUTIONS GRADED A+
⫸ Natural Selection Answer: Non-random process where individuals
with advantageous traits survive and reproduce more successfully.
⫸ Darwin's Finches Answer: Variation in beak shape among finch
species led Darwin to propose adaptation through natural selection.
⫸ Speciation Answer: Formation of two species from one original
species.
⫸ Allopatric Speciation Answer: Speciation caused by geographic
isolation.
⫸ Sympatric Speciation Answer: Speciation occurring in the same
geographic area due to reproductive isolation or chromosomal changes.
⫸ Gene Pool Answer: Collection of all alleles present in a population.
⫸ Allele Frequency Answer: Rate at which a specific allele appears in a
population.
, ⫸ Hardy-Weinberg Equilibrium Answer: States that allele and genotype
frequencies remain constant unless evolutionary forces act on the
population.
⫸ Hardy-Weinberg Assumptions Answer: Infinitely large population;
two alleles at a gene locus; no mutation, migration, emigration, or
selective pressure.
⫸ p Answer: Frequency of the dominant allele.
⫸ q Answer: Frequency of the recessive allele.
⫸ p + q = 1 Answer: Equation representing total allele frequency.
⫸ p² Answer: Frequency of homozygous dominant genotype.
⫸ 2pq Answer: Frequency of heterozygous genotype.
⫸ q² Answer: Frequency of homozygous recessive genotype.
⫸ p² + 2pq + q² = 1 Answer: Hardy-Weinberg equation for genotype
frequencies.
