significance of mitosis | Class 12 Biology About This Video ........................ In This Video Lecture You Will Learn Basic Concept Of significance of mitosis Crossing over and random assortment of chromosomes are two significant happenings of meiosis. During crossing over, parental chromosomes exchange segments with the progeny of very same parents, i.e., brothers and sisters are not identical to each other. during anaphase the separation of homologous chromosomes is random, which gives modifications in the genome. These variations are not only the bases of evolution, but also make every individual specific, particular and unique in his characteristics. Even in plants, thus having the number of chromosomes in each, which is restored after Had meiosis not been the process, the chromosome number may have been doubled fertilization and maintains chromosome number constant generation after generation. very wide range of variety of gametes. Both these phenomena cause variations and Meiosis usually takes place at the time of sexual cell (gamete) formation, spore formation each other which results in a large number of Recombination. At the same time after every generation. Can you imagine the consequences? About This Channel..................... I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources. One-stop destination for all biology lectures. _ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial _ The videos are categories under various heading to make the students life simplified Visit My Other Channel Playlist .....................
