Problem
Find the area enclosed between y = x² and y = 2x in the first quadrant.
1
Find the points of intersection
Set the curves equal: x² = 2x → x(x - 2) = 0, so x = 0 and x = 2.
2
Identify which curve is on top
On (0, 2), 2x > x², so y = 2x is the upper curve.
3
Set up the area integral
A = ∫₀² (2x - x²) dx
4
Integrate term-by-term
A = [ x² - x³/3 ]₀²
Final Answer
A = 4/3 sq. units
Quick Answer
What is a Punnett square?
A Punnett square is a grid used to predict offspring genotypes from a genetic cross between two parents. The rows and columns represent the gametes (alleles) each parent can contribute. Each cell shows the genotype of an offspring receiving one allele from each parent. The fractions or percentages of each genotype and corresponding phenotype are read directly from the grid. Monohybrid crosses use a 2x2 grid; dihybrid crosses use a 4x4 grid.

FAQ
Frequently asked questions.
What does the 3:1 ratio mean?
In a monohybrid cross of two heterozygotes (Aa x Aa), the offspring phenotypes appear in a 3:1 ratio: three with the dominant phenotype, one with the recessive. This is because the genotype ratio is 1 AA : 2 Aa : 1 aa, and both AA and Aa express the dominant phenotype. The 3:1 ratio is a classic prediction of Mendel's law of segregation.
How does a dihybrid cross work?
A dihybrid cross involves two traits, each with its own pair of alleles. Two heterozygous parents (AaBb x AaBb) each produce four types of gametes (AB, Ab, aB, ab), giving a 4x4 Punnett square with 16 cells. By the law of independent assortment, the resulting phenotype ratio for two simple-dominance traits is 9:3:3:1.
What is a sex-linked trait?
A sex-linked trait is one whose gene is on a sex chromosome (X or Y). X-linked recessive traits affect more males than females because males have only one X chromosome. In a Punnett square involving sex-linked traits, you must track which chromosome (X or Y) carries the allele, and probabilities differ between male and female offspring.
How does codominance differ from simple dominance?
In simple dominance, the heterozygote shows the dominant phenotype only. In codominance, both alleles in the heterozygote are expressed simultaneously (think AB blood type: both A and B antigens present). The phenotype ratio for codominance is 1:2:1, matching the genotype ratio, because each genotype produces a distinct phenotype.
How accurate is AskSia?
AskSia is engineered for accuracy on standard high school and college coursework. Accuracy comes from subject-specialized models, a symbolic verification pass that catches arithmetic errors, and a self-check step that re-derives the answer before showing it to you.
Can I get practice problems and flashcards?
Yes. After any solve, ask Sia to generate similar practice problems at SAT, ACT, AP, IB, or college difficulty, or build a flashcard set on the underlying concept in one tap. Useful for exam prep and spaced repetition before a quiz, midterm, or final.
How much does AskSia cost?
AskSia has a free plan that includes daily solves across all subjects. AskSia Pro and Super include unlimited solves, advanced subjects, the full AI tutor companion, exports, and priority response speed. See pricing for details.
