Genes in Population | Vegetable Breeding

After reading this article you will learn about the gene and its role in population. Genetically defined, a genetic population is a spatial-temporal group of conspecific interbreeding individuals. All genetic information distributed among an interbreeding group of individuals collectively form a gene pool. The gene pool concept is best represented by small isolated colonies whose members can interbreed in a [...]

3 Main Types of Gene Action | Vegetable Breeding

This article throws light upon the following three main types of gene action. The types are: 1. Additive Gene Action 2. Dominance Gene Action 3. Epistasis. Type # 1. Additive Gene Action: When the genes act in such a way that substitution of one allele for another produces same plus or minus effect regardless of other gene (s) and the [...]

Hardy-Weinberg Equilibrium of Gene | Vegetable Breeding

After reading this article we will learn about the Hardy-Weinberg equilibrium of gene. In a large random mating population, both gene and genotype frequencies remain constant from generation to generation, in absence of migration, mutation and selection. These properties of a population were first demonstrated by Hardy and Weinberg independently in 1908, and are generally known as Hardy-Weinberg law. If [...]
