Chapter: 1 REPRODUCTION IN ORGANISM a) It helps in continuity of species generation after generation. b) It helps in transferring of genetic characters. c) It helps in increasing the no. of species. d) It helps in leading to evolution. Sexual reproduction is a better mode of reproduction. Because it results in genetic variation, evolution and more chance of survival. Because they are morphologically and genetically similar. Yes this statement is always true. Because it shows genetic variation thus more chance of survival advantages. Progeny formed from asexual reproduction Progeny formed from sexual reproduction Individuals are genetically identical Individuals show genetic variation Only mitotic divisions takes place Both meiotic and mitotic divisions takes place Formed from single parent Formed by two parents of opposite sex Asexual reproduction Sexual reproduction Uniparental Biparental No fusion and formation of gametes Fusion and formation of ga...
