Asexual reproduction is a form of reproduction in which the number of chromosomes or the fusion of gametes is not altered.
Being genetically identical to the parent is advantageous for organisms when the environment changes fast, and reproduction is needed.
A gamete (a reproductive cell with one set of chromosomes, like an egg or sperm) combines with another to form a zygote, eventually developing into an organism of cells with two sets of chromosomes. Sexual reproduction is a type of reproduction that involves this complex life cycle (diploid).
The advantages of sexual reproduction are numerous. Several instances include:
more genetic variation
immunity against contagious diseases
fewer genetic diseases
Evolutionary fitness has increased

Hi there!
This answer entirely depends on what you mean. The largest type(species), or the largest known? Well, either way, I have an answer for you.
The largest type is a Hyperion.
The largest KNOWN is The General Sherman Tree! And it's still growing. At the base, its circumference is 31 meters.
Have a nice day!
Each "human body cell" has 46 chromosomes. But human sex cells have 23 unpaired chromosomes in each cell. Sex cells are created by a special type of cell division, Meiosis.

In the 1950's, natural chemists Stanley Miller and Harold Urey, led a test which exhibited that few natural mixes could be shaped suddenly by reenacting the states of Earth's initial climate. In the wake of enabling the examination to keep running for multi week, they broke down the substance of the fluid pool.
The Miller– Urey trial (or Miller analyze) was a concoction explore that mimicked the conditions thought at an opportunity to be available on the early Earth, and tried the compound beginning of life under those conditions.
