Dominant and recessive genes are a big part of our lives. Dominant genes using are more common and only require one parent to have the gene. Dark colored hair is an example of a dominant gene. Recessive genes are less common and show up when both parents have the same gene. There are not as many Dominant or recessive

Glofish are a vibrant species of fish that glow in the dark. It was originally made in singapore with the actual fish being used was a zebrafish, the GloFish are now making their way to american homes. Their extreme colors come in red purple yellow green blue and pink. GloFish are not harmful to the environment at home but if they got out they could do real damage. Becoming an invasive species they could grow in number, larger than any other fish in the area, and will need to feed on the other organisms foods. That could be really bad even make some species go extinct.
