Some asexual lineages have also developed novel mechanisms to substitute sex and mimic its evolutionary advantages.doi:10.1016/B978-0-12-809633-8.20529-3I. SchnK. MartensEncyclopedia of Reproduction (Second Edition)
Our findings indicate that Hox genes regulate asexual reproduction via the emergence and modulation of A/P segmentation and behavior in adult animals. We previously identified requirements for the Wnt signaling genesβ-catenin, apc, dshB, andwnt11-6as well as the TGF-β signaling genesactR-1ands...

What are the different types of asexual reproduction and how do they work? How does parthenogenesis differ from other forms of asexual reproduction? List down the differences between sexual and asexual reproduction. What are the similarities between the sexual and asexual reproduc...
Asexual Reproduction:In biology, asexual reproduction is a reproductive method that does not involve the opposite union of sex cells. The newly created individuals are genetically and physiologically similar to each other. It can be found in both multicellular and unicellular organisms. There will be...
another kind of asexual reproduction. Yeast cells can reproduce by budding. The cell wall pushes out, and the cell nucleus moves toward the bud. The nucleus divides and one new nucleus moves into the bud. The other nucleus stays in the parent cell. The bud remains attached to the parent ...
1. The asexual reproduction is the common mode of reproduction in organisms that have a relatively simple organisation like algae and fungi and they shift to sexual method of reproduction just before the onset of adverse conditions. 2. Asexual (vegetat
These autonomous females don't need a mate to give birth. And new research suggests that asexual reproduction may even have evolutionary advantages.
Carassius gibeliorepresents a unique example of a species where sexual and asexual forms coexist [34]. Hence, this species constitutes an object of study to elucidate the evolution of sexuality and asexuality in animals, and the mechanisms responsible for the stable coexistence of sexual and asexual...
