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 [...]
In this article we will discuss about the linkage and recombination of genes. Morgan and his group observed in Drosophila that when the two genes in a dihybrid cross were situated on the same chromosome, the proportion of parental gene combinations were much higher than the non-parental type or new combinations (also called recombination) of genes. They also found that [...]
