Number of goldfish to average mass of each goldfish

1=350
5=300
20=200
50=100
Lack of competition with other fish is an environmental factor and increases how large goldfish can grow
Lack of competition with other fish changes the genetics of the goldfish and increases how large goldfish can grow

These statements are partially correct. Lack of competition with other fish can indeed lead to larger growth in goldfish, as they do not have to compete for resources such as food. However, it does not directly change the genetics of the goldfish. The genetic potential for growth is determined by the goldfish's genetic makeup, which is inherited from its parents. Lack of competition simply allows the goldfish to reach its maximum potential size.
