Linkage and Recombination (Part 1): Chromosomal Theory, Linkage & Crossing Over

Genetics is a significant branch of biology concerned with the study of genes, genetic variation, and heredity in organisms. For example, there is human genetics, mouse genetics, fruit fly genetics, etc. So, do you know where genes are located? Every single living organism of the universe consists of lively cells (except viruses), and the …

Relationship between plant breeding and other biological sciences

Introduction Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. It started with sedentary agriculture and particularly the domestication of the first agricultural plants. The development of plant breeding as a special feild of study has been associated with and dependent upon …
