<span>Genetic variation is introduced as a result of the distinct crossing over of chromosomes in both phases of prophase. In the meiosis process, there can also be mutations in the s phase which are very unpredictable and can result in some very significant variations depending on where the coding is. by independent assoartment and 3 by mutations in s phase. Because of the way that </span>meiosis is set up it allows for the offspring to be either very similar to the parents or can even be very different from these factors.
Asexual: Offspring arise from single organism
Sexual: Genetic information from two organisms (male and female), where one produces a motile gamete (male) that travels to fuse with a larger stationary gamete produced by other (female).
Internal Fertilization: Union of an egg cell with a sperm during sexual reproduction inside the body of a parent.
External Fertilization: The sperm cell reunites with the egg cell in the open, rather than inside the body of a parent.
:) I'm sure you can figure it out from the information I stated above
Known as the Influenza A virus subtype H5N1, or more commonly known as the Avian Flu/Bird Flu, H5N1 is enzootic (maintained within a population) globally in many bird populations. According to recent word from the World Health Organization, as well as the United Nations Food and Agriculture Organization, H5N1 pathogenicity is gradually continuing to rise in endemic areas. However farmed birds are held in check by vaccination, and thus far there is no evidence of sustained human-to-human transmission of the H5N1 virus. The number of worldwide outbreaks being reported are steadily decreasing.
