Difference between asexual and sexual reproduction videos


Sexual reproduction involves two parents and the joining of male and female gametes during fertilisation. The offspring inherit a mixture of genes from both parents, so are different to each other and their parents. The advantages of sexual reproduction: In asexual reproduction there is only one parent.

The offspring are clones of the parent and each other. The advantages of asexual reproduction include: The disadvantages of sexual reproduction: The disadvantages of asexual reproduction include: Bacteria, such as E. An advantage of this is that they can produce many bacteria very quickly.

A disadvantage is that all of the bacteria are genetically identical. If an antibiotic was used on the bacteria, then all of them would die.

The population would be wiped out. The only way for variation to be introduced into the population is by random mutation. Most animals reproduce sexually, for example, rabbits.

The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring.

A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the specieshowever, outweighs this disadvantage.

If a disease were to hit the rabbit population, then perhaps not all of the rabbits would be affected because of the variation in the population.

This means that some individuals would survive and be able to reproduce and generate more offspring. Some fungi are able to reproduce both sexually and asexually.

Fungi reproduce using spores which they release into the environment. A new fungus will grow from the spore.
