Different between sexual and asexual reproduction

Answer» Sexual Reproduction involves two parents. Asexual Reproduction involves only one parent
\tOccurs in prokaryotic microorganisms and in some eukaryotic unicellular and multicellular organisms, lower invertebrates and plantsOccurs almost in all types of multicellular organisms including humans, animals, and higher plants.It is uniparental.It is usually bi-parental.Gametes are not formed.Gametes are formed.Somatic cells of parents are involved.Germ cells of parents are involved.No fertilization occurs.Fertilization takes place.No involvement of reproductive organs.Presence of fully developed reproductive organs.Only mitosis type of cell division occurs.Both meiosis and mitosis type of cell division occurs.The progeny and the parent are genetically identical.The progenies will be genetically different from the parents.Characteristics of only one parent are inherited.Characteristics of both parents are inherited.The genes and genetic material are just multiplied and passed on to new organisms from the parent.The genetic material undergoes intermixing from both parents to form a new set of genetic material.Multiplication is very rapid and takes less time.Multiplication is not so rapid and takes a longer time to complete.The number of offsprings produced may vary from two to many.The number of offsprings produced is comparatively lower.No evolutionary significance.Has evolutionary significance in the population.Bacterial fission, fragmentation, spore formation, budding of hydra are different types of asexual reproduction.Syngamy, external fertilization, and conjugation are different types of sexual reproduction.\t
\tAsexual ReproductionSexual ReproductionInvolves reproduction through any part of the body. Male and female gametes are absent.Involves fusion of male and female gametes.It is a simple process of cell divisionThe fusion of male and female gametes forms zygote from which develops a new individual. This process is known as ‘fertilisation’.No mixing of genetic material. Hence less variation is observed.Mixing of genetic material takes place. Hence it shows great extent of variation.It is a rapid process during favourable conditions.It is a slower process.Ex: Binary fission in amoeba, budding in hydraEx: reproduction in multi-cellular organisms.\t
