Where can you find pictures of genetic mutations?
Evaluate the significance of mutations and repair of mutations to the evolution of sexual reproduction?
Mutations differ and change according to many factors: 1- Site of occurrence: -Genetic mutations -Chromosomal mutations 2- The inheritance: -Somatic mutations -Gamete mutations 3- The origin: -Spontaneous (natural) mutations -Induced mutations 4- The harmful OR useful effects: -Undesirable mutations -Desirable mutations

Genetic mutations are not always harmful. A lot of mutations have a positive effect on the host. Some genetic mutations may help the host endure certain conditions in the environment, or eat certain food, or resist a certain superbug or virus, etc etc. However, some mutations can be harmful. Sometimes our little enzymes workers make mistakes and it can cause a "harmful" genetic mutation, such as a third leg or arm, or a third nipple…
Nuclear radiation can cause genetic mutations in our DNA, which can cause cancers. If the genetic mutations occur in the germ cells, then our gametes (sperm and egg cells) could have genetic mutations that could be passed on to our offspring. Also, if radiation levels are high enough, people can get radiation sickness, which can be fatal.
No. Genetic mutations lead to changes in the gene. This results in a (possible) new allele. Genetic drift is the change in frequency of an allele in the population due to chance. The smaller the population the bigger the chance on genetic drift (like it is more likely to coin flip 10 heads in a row then 1000 heads) while on the other hand the bigger the population the bigger the chance new alleles will…
