sex-linked inheritance

  The chromosomes present in the diploid cells of the majority of the sexually reproducing animals are of two types: autosomes bearing genes for somatic characters and sex chromosomes bearing genes for sex.  Sex chromosomes also carry some genes for non-sexual characters such as colour blindness and haemophilia.  Such genes which are always associated with … Read more

DNA Structure & Function, DNAReplication,

DNA: STRUCTURE   DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the … Read more

Diversity of organism

  Each organism is different from other organisms. The total number of species living on the planet is imprecisely known and published estimates vary from 12 million to over 100 million. This is because there are large numbers of species yet undiscovered and undescribed, and there is not always agreement on whether certain organisms should … Read more

Remote sensing- GIS and its application

    Remote Sensing Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation. In current usage, the term “remote sensing” generally refers to the use of satellite- or aircraft-based sensor technologies to detect and classify objects on Earth, … Read more
