- Genetic variation is important to evolution because it helps to maintain the health of a population by constituting alleles that may be useful in overcoming stresses such as diseases and pests. Without genetic variation, some of the fundamental mechanisms of evolutionary changes would not operate.

- While sexual reproduction provides variety in the offspring and natural selection, asexual reproduction will produce clones with all the genetic faults that the parent has in …the offspring (this is not the case if the offspring are mutated). There are some drawbacks to sexual reproduction though.

Contents: Mitosis and Meiosis Meiosis and Genetic Diversity. Sexual reproduction uses the process of meiosis to increase genetic diversity. Offspring created through asexual reproduction (mitosis) are genetically identical to their parent, but the germ cells created during meiosis are different from their parent cells.

Ways in Which Sexual Reproduction Provides Greater Genetic Diversity Than Asexual Reproduction So in order to form a new organism, two gametes -- the sex cells, sperm and egg -- must fuse, further mixing the genes to produce more genetic diversity. Asexual reproduction is one organism dividing into two organisms without shuffling its genes, so the offspring has the same version of genes as did the parent.

7 Advantages and Disadvantages of Sexual Reproduction List of Disadvantages of Sexual Reproduction. 1. It requires two parents. One of the biggest benefits of asexual reproduction is that any asexual organism can produce offspring on its own. Unfortunately, reproduction isn’t as easy as for sexual organisms, which need a male and female in order to reproduce.

Meiosis, inheritance and variation Genetic variation is increased by meiosis. During fertilisation20, 1 gamete21 from each parent combines to form a zygote. Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.

What are The Advantages of Sexual Reproduction? The sexual reproduction has many advantages over asexual reproduction. In asexual reproduction, t offsprings are almost identical to their parent because they have the same genes as their parent. So, mud genetic variation is not possible in asexual reproduction. This is a disadvantage of asexual reproduction because it inhibits the further evolution of the organism. In sexual reproduction the offsprings, although similar to their parents, are not identical to them or to one another. This is because the offsprings receive some genes from the mother and some from the father.

Explain how independent assortment, crossing over, and random fertilization contribute to genetic variation. ? Crossing over Another mechanism that increases genetic variation is the process of crossing over, during which homologous chromosomes exchange genes.Crossing over = The exchange of genetic material between homologues; occurs during prophase of meiosis 1.This process: i ï occurs when homologous portions of two nonsister chromatids trade. Places during Prophase, I-x shaped chiasmata become visible at places where this homologous strand exchange. occursrossing over = The exchange of genetic material between homologues; occurs during prophase of meiosis 1.

What features of meiosis are important in sexual reproduction? Why is meiosis important to heredity? Because the chromosomes of each parent undergo genetic recombination during meiosis, each gamete, and thus each zygote, will have a unique genetic blueprint encoded in its DNA. In other words, meiosis and sexual reproduction produce genetic variation. In meiosis, A cell undergoes reduction division and, a human cell which is of 46 chromosomes, forms 4 cells of 23 chromosomes each. During the union of Gametes, 23 chromosome from the father's sperm and 23 from mother's egg cell fuse to form a diploid zygote of 46 chromosomes, and later embryo. If this meiosis doesn't happen a child would be having 92 chromosomes which is impossible at all costs.

Evolution Variation comes from mutations in the genome, reshuffling of genes through sexual reproduction and migration between populations (gene flow). Despite the constant introduction of new variation through mutation and gene flow, most of the genome of a species is identical in all individuals of that species.

- Gamete Fusion. The third way that sexual reproduction provides greater genetic diversity than asexual reproduction is through the process of fertilization, or gamete fusion. Gametes contain only half the amount of DNA of a normal cell, so two gametes must fuse to form a new cell that will develop into a new organism.he third way that sexual reproduction provides greater genetic diversity than asexual reproduction is through the process of fertilization, or gamete fusion.

Gametogenesis Meiosis is the type of cell division that allows sexual reproduction, since it reduces the number of chromosomes of the species to a half, making the combination of two gametes to form a new individual possible. (In some organisms, meiosis creates haploid gametophytes that by means of mitosis generate gametes.

Why asexual reproduction? When I took a course on genetics and evolution, I learned that recombination and sexual reproduction is advantageous compared to asexual reproduction. Sexual reproduction allows more combinations of DNA because of recombination, allowing more variations of species, causing natural selection to choose different variations of species to reproduce and share their genes to help the species from dying out.

Why is sexual reproduction more evolutionarily advantageous than asexual reproduction? However, sexual reproduction leads to a stronger mix of genes which allows a stronger species to evolve. It also gives rise to more complex organisms. Asexual reproduction is cloning ... just copying the exact same data present in the parent. There is no genetic recombination allowed in this format, unlike sexual reproduction. How often do you get a completely different image from a perfectly operating xerox machine photographing the same page from a book?

Sexual Reproduction The genetic diversity of sexual reproduction, observed in most eukaryotes, is thought to give species better chances of survival. Describe the benefits of sexual reproduction. The variation that sexual reproduction creates among offspring is very important to the survival and reproduction of the population.

Cooperative breeding Cooperative breeding causes the reproductive success of all sexually mature adults to be skewed towards one mating pair. This means the reproductive fitness of the group is held within a select few breeding members and helpers have little to no reproductive fitness. With this system, breeders gain an increased reproductive, while helpers gain an increased inclusive fitness.

- Sexual reproduction happens when a male gamete and a female gamete join. This fusion of gametes is called fertilisation. Sexual reproduction allows some of the genetic information from each parent to mix, producing offspring that resemble their parents but are not identical to them.

Biological Significance of Mitosis & Meiosis in Sexual Reproduction Significance of mitosis for sexual reproduction. Mitosis is important for sexual reproduction indirectly. It allows the sexually reproducing organism to grow and develop from a single cell into a sexually mature individual. This allows organisms to continue to reproduce through the generations.
