Mutation can result in many different types of change in sequences. Mutations in genes can either have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely. Mutations can also occur in nongenic regions.
Traits are the physical manifestation of your genes. Brown hair or blue eyes are examples of traits. Genes, are pieces of DNA which code for proteins, which subsequently result in traits. So, if you have a really long piece of DNA, a gene is a part of that DNA. That part gets 'transcribed' to mRNA, which gets 'translated' into protein. The protein is what is responsible for traits. Alleles are 'flavors' of genes. We all have 46 chromosomes (humans). 23 are from the mother and 23 are from the father.
