 * 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. E...

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.
