Chromosome mutations

1: How can mutations affect us as humans?
Some people may be affected by mutations and the results may be good, bad or it won't change anything but humans may be affected because if someone gets a negative mutation and it affects his system and he passes it to his children and family, that negative mutation could keep on passing through generations, another example would be if any person gets a positive mutation and it creates some sort of immunity or protection against some diseases, this mutation would keep on passing through those family's genes and it would make the society healthier and better equiped to survive. There are many other examples of genetic mutations be good or bad. There are many mutations that affect humans in physical and internal ways but I think that this kinds of mutations build some genes stronger so we could be better prepared and less harmed in the future.

Oreo Lab

1: Why is it important that each cell copies it's DNA exactly?
It is very important for the DNA of the cells to be exactly the same when it is duplicated because the DNA has all your genetic information and this information has to be kept the same for normal development of each part of the human body, If any cell duplicates and has the wrong DNA information, there would be a problem, the cell would continue dividing and the wrong genetic information would be past on. Also if the cells would want to make a certain type of cell for recovering a skin part of the body the cells would make more skin cells not hair cells or other type of cells that that part of the body needs, that would damage the process.

Monster's Lab questions

1) Why might one trait be more popular than others in a particular population?

There are many traits that are very common on people, for example the eye colors Brown against Blue, in this case Brown would be the dominant color and Blue would be the recessive color, Brown is very likely to be the next result of the offspring.

2) Is it possible for an offspring to have a phenotype that neither the father nor the mother has? Explain your answer.

Yes, although it is really rare for this to happen there can be a slight change of traits and the environment could also condition the phenotypes so that there wouldn't be a full compatibility, and if this happens there could be an offspring that has a different phenotype as their parents. Also the offspring´s grandparents could have had the traits that he has without the offspring's parents having it.
