Encased permanently in a high-transparency, optical-grade acrylic resin block (164 × 78 × 20 mm), this authentic biological preparation presents five genuine genetic corn cob (Zea mays) cylindrical cross-sections mounted side-by-side in horizontal sequence. Prominently titled \\\"Rule of Gene Isolation\\\" across the top, the specimen features sequential numerical labels (1 through 5) illustrating classical genetic crosses and kernel color segregation: pure-breeding homozygous recessive yellow \/ white kernels (1), pure-breeding deep red kernels (2), homozygous dominant dark purple \/ black anthocyanin kernels (3), F1 \/ testcross cob section displaying distinct Mendelian 1:1 or 3:1 kernel color ratios (4), and dihybrid F2 segregation cob displaying variegated 9:3:3:1 mixed aleurone pigmentation (5). Suspended securely within crystal-clear, non-yellowing acrylic, all five botanical preparations provide distortion-free 360-degree optical clarity from every perspective—allowing students, educators, and genetics researchers to count individual endosperm kernels, calculate real phenotypic ratios, and examine kernel aleurone layers without the kernel loss, insect damage, or weathering of dried agricultural corn cobs. An indispensable hands-on teaching specimen for genetics coursework, high school and university biology laboratories, STEM life science classrooms, and agricultural science curricula.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWHY YOU'LL LOVE IT\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eAuthentic Mendelian Genetics Specimen\u003c\/strong\u003e – Preserves 5 genuine genetic corn cob cross-sections demonstrating Mendel's Law of Segregation (Rule of Gene Isolation).\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003e5 Numbered Genetic Test Stages (1–5)\u003c\/strong\u003e – Sequential labels clearly illustrate pure parent strains (1, 2, 3), monohybrid segregation (4), and multi-allele \/ dihybrid phenotypic ratios (5).\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eReal Hands-On Data Counting\u003c\/strong\u003e – Enables students to count actual purple and yellow kernels on the cob face to empirically calculate classic 3:1 and 9:3:3:1 phenotypic ratios.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eExceptional Botanical Kernel Detail\u003c\/strong\u003e – Delivers magnified observation of corn cob rachis cores, pericarp surfaces, aleurone pigmentation, and starch endosperm textures.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eGenerous Optical-Grade Acrylic Monolith\u003c\/strong\u003e – Solid 164 × 78 × 20 mm clear resin block provides comprehensive panoramic viewing and substantial paperweight presence.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003ePermanent, Clean \u0026amp; Odorless\u003c\/strong\u003e – Durable acrylic casing seals delicate agricultural grains permanently, completely free of pests, grain beetles, mold, or drying shrinkage.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eEssential Life Science Teaching Tool\u003c\/strong\u003e – An outstanding visual aid for high school AP Biology, university genetics lectures, STEM classrooms, and agricultural education.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003ePERFECT FOR\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eGenetics instructors, biology educators, high school and college STEM classrooms, agronomy students, science fair demonstrations, and distinctive natural history gift collections.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e E2110\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecimen:\u003c\/strong\u003e 5 Genetic Corn Cob Sections (Zea mays, Poaceae)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Optical-Grade Acrylic Resin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 164 × 78 × 20 mm (approx. 6.5 × 3.1 × 0.8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Crystal Clear with Natural Yellow, Red, and Purple Corn Kernels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Horizontal Rectangular Monolith with Numbered Labels (1–5)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003e*Notice: Price is for retail.
