Cloning And Selective Breeding

What is Asexual and sexual replication?

Asexual:
Asexual reproduction is reproduction by one single elevate so it doesnt need a partner to create an offspring. It gets the genes and traits from that raise only. The reproduction doesnt use meiosis or binding as it is not needed. It is flirt witht for single celled organisms. For example in bacterium does not need two p arents to creates and offspring, only one parent is required.

Advantages:
1. large numbers of offspring are reproduced very speedily from only one parent when conditions are favorable.
2. Large colonies stomach form that can out-complete other organisms for nutrients and water.
3. Large number of organisms mean that species may survive when conditions or the number of predators change.

Disadvantages:
1. Hard for species to educate/ and or vary.
2. Most species that asexually reproduce are underage organisms (single celled bacteria or protists), although there are some plants that are known to asexually reproduce.

Sexual:
Sexual reproduction is producing a new organism by combining the genes, traits etc from BOTH organisms (parents). The unconscious process involves meiosis having the exact number of chromosomes from both parents (23 from each).



It also includes saturation which fuses two of the gametes and the restoration of the original number. When meiosis occurs the chromosomes of each couple crosses over to create homologous pairs.

Most animals (including humans) and plants reproduce sexually. sexually reproducing organisms feature two sets of genes for either trait (called alleles). Offspring inherit one allele for each trait from each parent, thereby ensuring that offspring have a combination of the parents genes. Having two copies of every gene, only one of which is expressed, allows deleterious alleles to be masked, an advantage believed to have led to the
evolutionary development of diploid.

Advantages:
1. produces a more good offspring
2. Production of many new gene...If you want to get a full essay, order it on our website: Ordercustompaper.com
