2. Give the expected phenotypes and state whether it is homozygous or heterozygous
_______% white (homozygous or heterozygous)
_______% red (homozygous or heterozygous)
_______% fire and ice (homozygous or heterozygous)

Selective Breeding
Selective breeding (or Artificial Selection) is when humans choose desirable traits in parent organisms, hoping to get those same desirable traits in the offspring. Selective breeding is used by pet breeders, farmers, and ranchers. Watch the video below to see how humans have created the dog breeds we see today through selective breeding.
