Hydra vulgaris constantly replenish the cells in their heads and grow new ones to reproduce asexually. But gene expression analyses reveal that regenerating a head after an injury is a very different ...

The questions in this quiz are suitable for GCSE biology students studying asexual reproduction, sexual reproduction, meiosis and gamete formation, advantages and disadvantages of sexual and ...

Imagine a gene that promotes sexual reproduction, such as by making it more likely that a plant will reproduce via sexually produced seeds as opposed to some asexual process (e.g., budding ...

Those outlier liaisons gave whiptails robust heterozygosity, which has been preserved by the identical replication—essentially, cloning—that occurs in asexual reproduction. It’s a genetic ...

The finding may offer insight into a long standing question in evolutionary biology about what forces cause species to choose sex over asexual reproduction and vice versa, he said. On paper, ...

(Mutations do create a minor amount of change.) If asexual reproduction survives at all, conditions must sometimes favor it, even in competition for a niche with sexually reproducing species.

For mammals, female self-sufficiency is not an option when it comes to reproduction. Parthenogenesis, asexual reproduction, is precluded by the need for two separate genomes with individual ...

Researchers at the University of Texas at Arlington discovered how the flowerpot snake, with three sets of chromosomes, can ...
