AIIMS 2018 Biology Question Paper with Solutions - 27th May 2018 Evening Shift

UNIT I: Reproduction 

• Reproduction in organisms: Reproduction, a characteristic feature of all organisms for continuation of species; Modes of reproduction – Asexual and sexual; Asexual reproduction; Modes-Binary fission, sporulation, budding, gemmule, fragmentation; vegetative propagation in plants. 

• Sexual reproduction in flowering plants: Flower structure; Development of male and female gametophytes; Pollinationtypes, agencies and examples; Outbreeding devices; Pollen-Pistil interaction; Double fertilization; Post fertilization events Development of endosperm and embryo, Development of seed and formation of fruit; Special modes-apomixis, parthenocarpy, polyembryony; Significance of source and fruit formation. 

• Human Reproduction: Male and female reproductive systems; Microscopic anatomy of testis and ovary; Gametogenesis spermatogenesis & oogenesis; Menstrual cycle; Fertilization, embryo development up to blastocyst formation, implantation; Pregnancy and placenta formation (Elementary idea); Parturition (Elementary theory); Lactation (Elementary idea). 

• Reproductive health: Need for reproductive health and prevention of sexually transmitted diseases (STD); Birth control Need and Methods, Contraception and Medical Termination of Pregnancy (MTP); Amniocentesis; Infertility and assisted reproductive technologies – IVF, ZIFT, GIFT (Elementary idea for general awareness).

UNIT II: Genetics and Evolution

• Heredity and variation: Mendelian Inheritance; Deviations from Mendelism-Incomplete dominance, Co-dominance, Multiple alleles and inheritance of blood groups, Pleiotropy; Elementary idea of polygenic inheritance; Chromosome theory of inheritance; Chromosomes and genes; Sex determination-In humans, birds, honey bee; Linkage and crossing over; Sex-linked inheritance-Haemophilia, Colour blindness; Mendelian disorders in humans-Thalassemia; Chromosomal disorders in humans; Down's syndrome, Turner's and Klinefelter's syndromes. 

• Molecular basis of Inheritance: Search for genetic material and DNA as genetic material; Structure of DNA and RNA; DNA packaging; DNA replication; Central dogma; Transcription, genetic code, translation; Gene expression and regulation-Lac Operon; Genome and human genome project; DNA fingerprinting. 

• Evolution: Origin of life; Biological evolution and evidence for biological evolution from Paleontology, comparative anatomy, embryology, and molecular evidence); Darwin's contribution, Modern Synthetic Theory of Evolution; Mechanism of evolution-Variation (Mutation and Recombination) and Natural Selection with examples, types of natural selection; Gene flow and genetic drift; Hardy-Weinberg's principle; Adaptive Radiation; Human evolution.

UNIT III: Biology and Human Welfare

• Health and Disease: Pathogens; parasites causing human diseases (Malaria, Filariasis, Ascariasis. Typhoid, Pneumonia, common cold, amoebiasis, ringworm); Basic concepts of immunology-vaccines; Cancer, HIV, and AIDS; Adolescence, drug and alcohol abuse. 

• Improvement in food production: Plant breeding, tissue culture, single-cell protein, Biofortification; Apiculture and Animal husbandry. 

• Microbes in human welfare: In household food processing, industrial production, sewage treatment, energy generation, and as biocontrol agents and biofertilizers.

UNIT IV: Ecology and environment

• Organisms and environment: Habitat and nic

Here are some tips for candidates who are preparing for the AIIMS examination: 

• Preparing a proper schedule and spending a reasonable amount of time on each subject. Just making the schedule is not enough. Following it is equally important.  

• Make notes and collect these revision notes subject-wise so that it helps you at the crucial stage.  

• Start with the simple topics to understand the basics first and then move on towards the complex concepts.  

• Once all the topics are well understood, proceed towards solving Question Papers for practice.  

• Don't stress your mind during the exam preparation, keep a calm mind, maintain a balanced diet.

AIIMS Syllabus covers questions from Chemistry, Biology, Physics, General Knowledge, Aptitude, and Logical Thinking. 

According to the science curriculum, it will have a difficult standard of 12th Grade. NCERT Books of Grade 11 & 12 Syllabus are applicable by CBSE for AIIMS. 

To qualify for AIIMS, passing the 12th Grade with an aggregate of 60% (for the general category) in Physics, Chemistry, Biology, and English are needed.

But at the same time, after passing 12th Grade with 60%, focusing on the AIIMS preparations is all that matters. You can still crack it.
