Summary Introduction
Concept introduction: Monohybrid and dihybrid cross help to study the dominant allele and the linking of the genes. The parents in the monohybrid and dihybrid crosses are true breeding and homozygous dominant or recessive for the given trait. The parents give rise to the heterozygous F1 generation. The F1 generation is self- crossed to give F2 generation.
