asexual reproduction occurs in a form that is partly fission and partly budding; portions are constricted transversely or laterally, very much smaller than the whole animal, and these grow out into new animals which may separate or remain attached in chains. In Salps, chains are formed sometimes...

than asexual, although it is easier mechanically for an organism simply to divide into two or more individuals. Even many of the organisms that do exactly this—and they are not all the so-called primitive forms—every so often intersperse their normal asexual pattern with sexual reproduction. ...
inhox3RNAi animals, revealing a decrease in progeny size consistent with the increase in segmentation observed via physical compression (Fig.2d, e). Altogether, these data indicate that the planarian Hox genespost2bandhox3are required for A/P tissue segmentation associated with asexual reproduction....
One of the most fascinating aspects of human life is how we choose our mates. Animals also choose their mates, sometimes with a great deal of care. Mating systems are important to understand because they reflect the result of natural selection on mate ch
(whichcorrelateswith complexity and generation time); the size of the population; the degree of inbreeding versus outbreeding; and the relative amounts and position of haploidy and diploidy in the life cycle. It is clear, therefore, that the mode of reproduction influences the amount of ...
some species can reproduce asexually and, others like the egg-laying duck-billed platypus, buck the reproductive norms of their scientific classifications. Still, much of the reproduction across all species begins with the fertilization of an egg, and many of the species in the Kingdom Animalia ...
Sexual Reproduction As you all know, sexualreproductionis characterized by the fusion ofmaleandfemalegametes. When compared to asexual reproduction, sexual reproduction is considered as a better mode as there is a variation in thepopulation, along with the evolution of species. Genetically speaking, ...
