Advance Course AIIMS-SYLLABUS Biology syllabus The Molecular Basis Of Inheritance

The Molecular Basis Of Inheritance The molecular basis of inheritance refers to the underlying mechanisms by which genetic information is passed on from parents to offspring. It involves the study of the molecular structures and processes that govern the transmission, replication, and expression of genetic material. Key concepts and components of the molecular basis of…

Advance Course AIIMS-SYLLABUS Biology syllabus Klinefelter syndrome

Klinefelter syndrome Klinefelter syndrome, also known as 47,XXY syndrome, is a genetic disorder that affects males. It is characterized by the presence of an extra X chromosome in each cell, resulting in a karyotype of 47 chromosomes instead of the typical 46. The additional X chromosome is derived from either the mother or the father…

Advance Course AIIMS-SYLLABUS Biology syllabus Variation

Variation In biology, variation refers to the differences that exist between individuals of the same species. These variations can occur at various levels, including genetic, phenotypic, and environmental. Variation is important in biological systems as it provides the raw material for natural selection and evolution. It allows populations to adapt to changing environments and increases…

Advance Course AIIMS-SYLLABUS Biology syllabus Heredity

Heredity Heredity refers to the passing of genetic information from parents to offspring. It is the process by which traits, characteristics, and genetic material are transmitted from one generation to the next. The study of heredity is known as genetics. Heredity is based on the genetic material present in the cells of an organism. Genes…

Advance Course AIIMS-SYLLABUS Biology syllabus Genetics and evolution

Genetics and evolution Genetics and evolution are two interconnected fields of biology that study the inheritance and variation of traits in living organisms over time. Here’s a brief overview of each field: Genetics: Genetics is the branch of biology that focuses on the study of genes, heredity, and genetic variation. It examines how traits are…

Advance Course AIIMS-SYLLABUS Biology syllabus Post-Fertilization Events

Post-Fertilization Events Post-fertilization events in biology refer to the series of processes that occur after fertilization, leading to the development of an embryo and ultimately a mature organism. These events can be broadly divided into the following stages: It’s important to note that these events are complex and tightly regulated processes that involve intricate molecular,…

Advance Course AIIMS-SYLLABUS Biology syllabus Double Fertilization

Double Fertilization Double fertilization is a unique reproductive process that occurs in flowering plants (angiosperms). It involves the fusion of two sperm cells with two different female gametes, leading to the formation of two different structures: the zygote and the endosperm. Here is a step-by-step explanation of the process of double fertilization: Double fertilization ensures…

Advance Course AIIMS-SYLLABUS Biology syllabus Sexual reproduction in plants

Sexual reproduction in plants Sexual reproduction in plants is the process by which plants produce offspring through the fusion of male and female gametes. It involves the production of specialized reproductive structures, such as flowers, which contain the male and female reproductive organs. Here is an overview of the key aspects of sexual reproduction in…

Advance Course AIIMS-SYLLABUS Biology syllabus Vegetative Propagation

Vegetative Propagation Vegetative propagation is a method of plant reproduction in which new plants are produced from vegetative structures of a parent plant, such as stems, roots, and leaves, without the involvement of sexual reproduction (seeds). It is a form of asexual reproduction that allows plants to reproduce without the need for pollination, fertilization, and…

Advance Course AIIMS-SYLLABUS Biology syllabus Fragmentation

Fragmentation Fragmentation is a term used in computer science and data storage that refers to the process of dividing files or data into smaller pieces called fragments or blocks. It is a technique used for efficient storage and retrieval of data on disk drives. Here are some key points related to fragmentation in the context…
