The genes appeared in a later generation, they were dormant.
No, that is completely impossible. The reasoning behind it is because if its a large group of fish they're swimming back and forth ect, ect, it would be like counting a bowl of rice, but not being able to take any out. To get around these counting problems, scientists take data from just a small portion of the population called a sample. They take several samples and then use the average size of those samples to calculate an estimate of the entire population size.

Eukaryotes always have a cell membrane, but prokaryotes don't. Eukaryotic and Prokaryotic cells are both
building blocks of life in different organisms. The main difference of two is
in its structures. Eukaryotic cells contain organelles that are found
inside membranes, like the nucleus, which stores chromosomes and DNA.
Prokaryotic cells don't have a nucleus and no true chromosomes. Prokaryotic cells
are unicellular while eukaryotes are multicellular. The presence of
mitochondria, chloroplasts, and cell wall are all distinct to Eukaryotic cells.
Eukaryotic cells are found in animals and plants, while bacteria and archaea
have prokaryotic cells.<span>
<span>In terms of existence, prokaryotes have been on
Earth for millions of years; while eukrayotic cells have come to existence
through the process of evolution. </span></span>
