First, we will use the model brown alga Ectocarpus to reveal the fundamental genetic mechanisms by which sex chromosomes control reproductive and life cycle traits of broad importance to all eukaryotes, including sex determination and asexual reproduction
through parthenogenesis but also the control of gamete size and the regulation of developmental switches during the life cycle.
makes more sense mathematically, which led sexual reproduction to be a paradox.
Conn (1990) stated that asexual reproduction
was confirmed by continual propagation of laboratory clones only in tetrathyridia isolated from lizards, as reported by Specht and Voge (1965).
Geneticists long have bet on the success of sexual reproduction over asexual reproduction
based, in a large part, on the process known as Muller's ratchet, the mechanism by which a genome accrues deleterious and irreversible mutations after the host organism has lost its ability to carry out the important gene-shuffling job of recombination.
falciparum developing habits of asexual reproduction
like other Plasmodium sp (2).
It also establishes, for the first time, quantitative estimates of the relative rates of sexual and asexual reproduction
during the parasite life cycle.
Increasing resource allocations to sexual reproduction or asexual reproduction
can be at the expense of the other (Bazzaz et al.
are also brought to bear on the issue.
During asexual reproduction
, cells other than gametes develop a sporophyte through an asexual process without meiosis or fertilization called apogamy.
Yet evolution, which is concerned with differential reproductive success, has selected sexual over asexual reproduction
because of the benefit of genetic variation, which provides a higher survival rate of offspring (Barash, 1986; Rudin, 1997).
According to National Geographic, this is not the first reported asexual reproduction
among female sharks that do not have access to male counterparts.
vivax attack can indeed be the result of renewed asexual reproduction
of merozoites following a period of dormancy, as I hypothesise, then this would explain why parasites isolated from peripheral blood samples in recurrent malaria have sometimes proved to be genetically similar to those that were responsible for the primary clinical infection.
