This is made possible by several genetic adaptions. Giant pumpkin cells grow larger than regular pumpkins, and are composed of more water (up to 94%). They also lack genes that stop fruit growth, resulting in continuous expansion. [3] Once pumpkins grow so large, they tend to no longer be round but will flatten out under their own intense weight.
Sexual reproduction has many drawbacks, since it requires far more energy than asexual reproduction and diverts the organisms from other pursuits, and there is some argument about why so many species use it. George C. Williams used lottery tickets as an analogy in one explanation for the widespread use of sexual reproduction. [36]
Resource availability is essential for the unimpeded growth of a population. Examples of resources organisms use are food, water, shelter, sunlight, and nutrients.[1][2] Ideally, when resources in the habitat are unlimited, each species can fully realize its innate potential to grow in number, as Charles Darwin observed while developing his theory of natural selection.

The human practice of mating and artificially inseminating domesticated animals is part of animal husbandry. In some terrestrial arthropods , including insects representing basal (primitive) phylogenetic clades, the male deposits spermatozoa on the substrate, sometimes stored within a special structure.
