UPCAT Biology — Genetics & HeredityConcept Map
For visual learners attacking the UPCAT 2026, a Genetics & Heredity concept map is usually worth more than ten pages of linear notes. UP builds many Genetics & Heredity items around the same handful of relationships — spot them on a map and you recognise them at a glance in the Biology paper.
Exam context
The University of the Philippines College Admission Test is conducted by University of the Philippines and is scheduled for Mid-2026 (announced by UP Admissions). The Biology subtest is marked as "Core" in the official pattern, and Genetics & Heredity appears in position 6th of 7 in the UPCAT Biology review rotation. Passing mark: UPG ≤ 2.2 typical. Recent UPCAT 2026 papers have drawn roughly 20 questions from this subject.
