MONOHYBRIDE CROSS AND DIHYBRIDE CROSS -BIOLOGY

Image
  MONOHYBRIDE CROSS  Definition-: A monohybrid cross is a genetic mix between two individuals with homozygous genotypes which result in an opposite phenotype. e.g.-: Cross of pure tall and pure dwarf plants...... DIHYBRID CROSS A  dihybrid cross  describes a mating experiment between two organisms that are identically hybrid for two traits. ... Therefore, a  dihybrid  organism is one that is heterozygous at two different genetic loci. IN ESAY WAY-:                                                       THANK YOU!  FOLLOW FOR MORE LIKE THIS.

Notes with pdf, download PDF esily      Introduction-:    Every day life we come across several rovolving objects[ rigid body]. during                                          revolution partical of object follow a circular path about same point.     characteristics of circular motion-: Uniform circular motion( UCM)-:   During circular motion if the speed of the particle remains constant is called as uniform circular motion. -:The acceleration responsible for this motion is along the rediac and towards the center is called as centripetal acceleration UCM its magnitude is constant and its given by-:    Illustration-: circular motion of any particles of a fan rotating uniformly. Non-uniform circular motion-: The circular motion in which speed is not constant is called as non-uniform circular motion.

Reproduction in Lower and Higher Plants - Short NOTES for 12th PART -1

 * Notes, Imp Points, Definitions, and Diagrams  For Class 12th Biology Chapter 1 REPRODUCTION IN LOWER AND HIGHER PLANTS Based on HSC Syllabus. PART -1   Introduction:- Reproduction: -  Reproduction is the production of young ones like parents. Two categories of Reproduction:- 1) Asexual Reproduction         2) Sexual Reproduction 1.1 Asexual Reproduction Definition : It is the process resulting in the production of genetically identical progeny from a single organism and inherits the genes of the parent. Clones:  Morphologically and genetically identical individuals. Different Modes of Asexual Reproduction: -  1) Fragmentation: -  When multicellular organisms break into fragments, these fragments grow into new individuals. Example - Spirogyra 2) Budding: -  This mode of reproduction occurs by producing one or more outgrowths (buds) from the parent body. These buds on separation develop into a new individuals. Example - Yeast 3) Spore Formation :  Reproduction that occurs by flagellat
