Conversely, there are also species in which there is no sexual specialization, and the same individuals both contain masculine and feminine reproductive organs, and they are called hermaphrodites. The reason for the evolution of sex, and the reason(s) it has survived to the present, are still matters of debate.
Some of the many plausible theories include: that sex creates variation among offspring, sex helps in the spread of advantageous traits, that sex helps in the removal of disadvantageous traits, and that sex facilitates repair of germ-line DNA.
Life has evolved from simple stages to more complex ones, and so have the reproduction mechanisms.
Our speakers were outstanding and thanks to Lindsay Mazepa and BCIT, the 11 posters on the walls of the room were impressive!
Congratulations to the Winner of the 2017 Student Poster Award – Kyley Cross: "A Promising new Way to Interpret: Using Simultaneous Electroencephalography and Near-Infrared Spectroscopy.” All other poster titles and participants will be printed in the next edition of the CAET Newsletter.
Typically, prior to an asexual division, a cell duplicates its genetic information content, and then divides. In sexual reproduction, there are special kinds of cells that divide without prior duplication of its genetic material, in a process named meiosis.
The resulting cells are called gametes, and contain only half the genetic material of the parent cells.
