How Youâll Know if Something is Wrong. Symptoms are typically related to the cause of the high white blood cell count. If the cause is an infection, symptoms will typically appear as fever, lack of appetite, moodiness, and fatigue. If the infection is external there may be a rash, wound, or abscess.
Sexual reproduction is able to generate genetic variation in offspring because the process of meiosis randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gamete. The two gametes then randomly fuse to form a new organism.Genetic variation is one of the keys to evolutionary fitness. This is made possible because reproductive cells undergo meiosis, which is the process in which one cell divides twice to produce four sperm or four eggs.he two gametes then randomly fuse to form a new organism.

5.4.6 Explain how sexual reproduction promotes variation in a species. Sexual reproduction is important for promoting variation as even though mutations form new genes or alleles, sexual reproduction forms a new combination of alleles. There are two stages in sexual reproduction that promote variation in a species. The first one is during meiosis during which a large variety of genetically different gametes are produced by each individual. The second stage is fertilisation. Here, alleles from two different individuals are brought together to form one new individual.
