Furthermore, the obligatory phase of sexual reproduction in the mosquito midgut is not only prerequisite for transmission, but also enables meiotic recombination between genomes, with the consequent production of parasites with re-assorted genotypes. It results in new combinations of polymorphic genes, ...
Sexual reproduction evolved from asexual reproduction about 2 billion years ago. Prior to this prokaryotes were reproducing asexually. Sexual reproduction allows organisms to have greater genetic variation which is a key component to natural selection. Answer and Explanation:...

Three common systemic human fungal pathogens — Cryptococcus neoformans, Candida albicans and Aspergillus fumigatus — have retained all the machinery to engage in sexual reproduction, and yet their populations are often clonal with limited evidence for recombination. Striking parallels have emerged with fo...
Sexual reproduction (conjugation) in protozoan ciliates is induced by specific cell-cell interactions between cells of complementary mating types. The ancestral ciliate Blepharisma japonicum has two mating types, I and II. The substances that act as signaling molecules in this extracellular interaction ...

Traits that influence reproductive success and contribute to reproductive isolation in animal and plant populations are a central focus of evolutionary biology. In the present study we used an experimental approach to demonstrate the occurrence of environmental effects on sexual and asexual reproduction, ...
