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.
This diagram illustrates the two-fold cost of sex. If each individual were to contribute to the same number of offspring (two), (a) the sexual population remains the same size each generation, where the (b) asexual population doubles in size each generation. This idea is sometimes referred to as the two-fold cost of sexual
A few types of organisms, such as many fungi and the ciliate Paramecium aurelia, [11] have more than two "sexes", called mating types. Most animals (including humans) and plants reproduce sexually. Sexually reproducing organisms have different sets of genes for every trait (called alleles). Offspring inherit one allele for each trait from each ...

Bateman attributed the origin of the unequal investment to the differences in the production of gametes: sperm are cheaper than eggs. A single male can easily fertilize all of a female's eggs; she will not produce more offspring by mating with more than one male. A male is capable of fathering more offspring if he mates with several females.
