Hybridisation – Class 12 | Chapter – 2 | Biology Short Notes Series PDF

Hybridisation: Hybridization refers to crossing or interbreeding between genetically dissimilar plants or animals to obtain a hybrid. This can be an artificial or natural process. It is important to note that hybridization does not change the genetic composition of an individual, it creates variability by producing a new combination of the allele. The main goal of this process is to induce heterozygosity and reduce homozygosity in the genotypes of the population.

Types of Hybridisation

  • Interspecific hybridization: Interbreeding between individuals of different species within the same genus is called interspecific hybridization. For example, mule (male donkey x female horse)
  • Intraspecific hybridization: Interbreeding between individuals from the same species but belonging to different population, breed or cultivars is called intraspecific hybridization. For example, a European Wolf and an American Timber Wolf.

Procedure of Hybridisation

  • Selection of Plant
  • Homozygosity
  • Emasculation
  • Bagging
  • Tagging
  • Crossing
  • Harvestation
  • F1 Generation
