Teaching forms of asexual reproduction in living organisms using concept mapping approachAmaefuna Ijeoma Anthonia
Some species are capable of either sexual or asexual reproduction. The simplest organisms have no sex organs, so asexual reproduction is a necessity. Other species, such as corals, may reproduce either sexually or asexually, depending on conditions. Though it occurs infrequently, some species surpri...
In diploid organisms, sexual reproduction rearranges allelic combinations between loci (recombination) as well as within loci (segregation). Several studies have analyzed the effect of segregation on the genetic load due to recurrent deleterious mutations, but considered infinite populations, thus neglectin...
We are surrounded by a great diversity of life, yet it all has one very important thing in common: reproduction. Because we cannot live forever, we need to create new offspring to carry on our genes. This can be done through asexual reproduction, where an individual identical to the parent...
Asexual reproduction does not produce clonal populations of the brooding coral Pocillopora damicornis on the Great Barrier Reef, Australia. Coral Reefs 25:7-18.Sherman CDH, Ayre DJ, Miller KJ (2006) Asexual reproduction does not produce clonal populations of the brooding coral Pocillopora damicornis ...
We scored the ploidy level and the mode of reproduction of the plants using four methods: (1) Size variation in the pollen grains (only possible with male fertile plants): triploid plants have a disturbed meiosis and produce pollen of different sizes, whereas diploids produce regularly sized ...
Secondly, the etymology of the word asexual has always referred to a species that does not require sex for reproduction. Putting all this together, what i see here is a poorly chosen way to describe a persons lack of sexual desires. That’s ridiculous. Another word for it is a eunich wh...
mutations in asexual oribatid mites. Finally, some non-canonical form of sex (e.g. horizontal gene transfer between bdelloid rotifers26) in oribatid mites cannot formally be excluded, although it seems unlikely that this would result in more effective selection than common bisexual reproduction. ...
ability to persist in the short and long term, natural selection might act on the genetic controls of sexual and asexual reproduction in facultative asexual organisms, which in turn can alter the levels of genomic diversity, heterozygosity and effectiveness of selection in the population2,5,13,14...
This was done by assuming that per time step, there is a probability Rec1 that a “donor” agent meets a “recipient” agent within the reproduction radius. When they do meet, then there is a probability Rec2 for each locus in the recipient to be exchanged with the genotype of the ...
