DNA Sequencing in Genome Projects — NEET Biology
📚 Practice ConceptAre extensively used as a starting point in the sequencing of whole genomes as was done in the case of the Human Genome Sequencing Project, described later.
Match the following genetic patterns with their underlying mechanisms and associated conditions: Column I (Genetic Pattern) A. Pleiotropy B. Polygenic Inheritance C. Codominance D. Point Mutation E. Aneuploidy Column II (Underlying Mechanism/Description) I. A single gene affects multiple, seemingly unrelated phenotypic traits. II. Multiple genes contribute additively to a single phenotypic trait. III. Both alleles of a gene are fully expressed in the heterozygote. IV. Alteration of a single base pair in the DNA sequence. V. Gain or loss of one or more chromosomes. Column III (Associated Condition/Phenotype) P. Mental retardation, reduced hair/skin pigmentation Q. Human skin colour, showing a continuous gradient R. ABO blood grouping, where IA and IB are both expressed S. Sickle-cell anaemia, specifically the GAG to GUG substitution T. Down's syndrome, due to trisomy of chromosome 21
Through deep analysis of NEET and NTA, 88 of 90 questions from the NEET 2026 paper were matched straight from the MedicNEET Biology question bank.
