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.

Sexually reproducing organisms have different sets of genes for every trait (called alleles). Offspring inherit one allele for each trait from each ...
