Mr. Smith is colorblind. His wife, Mrs. Smith, has normal color vision, but her father was color blind. If they have eight children 4 boys and 4 girls, how many of the boys would you expect to be colorblind? Girls? HELP

So I would proceed into making a Punnett square. Women only are carrier towards colorblindness so there would be a very slim chance of them being colorblind. While males would not be affected at all. This is because the mother passed her X chromosome to the son and she doesn’t have the colorblind gene. So in conclusion 4 girls will be carriers while the males will not have colorblindess.

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.

Giga is the second highest prefix on the normal scale, the first is terra.
