Question

Based on the Punnett square below, what is the probability of the offspring being heterozygous? <!-- AI image prompt | slot:punnett_aa_x_aa_v3 | paste into Gemini/DALL-E/Midjourney: STRICT RULES — OBEY EVERY ONE OR THE IMAGE IS UNUSABLE:
(1) The image contains EXACTLY these text labels and nothing else: "A", "a", "Parent 1 (Aa)", "Parent 2 (Aa)", "AA", "Aa", "aa". (2) The following words MUST NOT APPEAR anywhere on the image, in any form, abbreviation, casing, or plural: heterozygous, homozygous, dominant, recessive, probability, phenotype, genotype, ratio, percent, %, 1/4, 1/2, 3/4. (3) ZERO arrows other than those explicitly described. ZERO icons or illustrations not explicitly described. ZERO highlighting/glow/circle around any structure. (4) ZERO title, heading, caption, watermark, signature, color legend, key, scale bar, page number. (5) Background: pure flat white (#FFFFFF). (6) ALL labels (when present) use identical typography (same font, size, weight) and identical leader-line style — no label is emphasized over another.

SUBJECT: Scientific textbook Punnett square, 1100x1100, white background. STRUCTURE: a 2x2 grid centered, each cell ~280px square, thin black borders. ABOVE the grid: two column headers, each one bold sans-serif uppercase letter — left column "A", right column "a". TO THE LEFT of the grid: two row headers — top "A", bottom "a". Above the column headers, small bold label "Parent 1 (Aa)". To the LEFT of the row headers (vertical orientation), small bold label "Parent 2 (Aa)". INSIDE the four cells, in large bold sans-serif: top-left "AA"; top-right "Aa"; bottom-left "Aa"; bottom-right "aa". All four cells share an identical neutral pale background — no cell is highlighted, colored differently, or emphasized. FINAL REMINDER: NO ratio numbers, NO probability percentages, NO words like "heterozygous" or "recessive" — only letters and the parent labels. -->
