dimples are a "birth defect" means that your muscles are too short thus pulling the skin causing this little holes, why do you think most babies have them? cause their muscles developed and they have a lot of baby fat same goes to people with a little extra fat
A translocation chromosomal mutation will result when two non-homologous chromosomes each broken by some sort of clastogen and then are swapped.
mutation means change in genetic structure..where as crossover means interchanging the genetic structure of two or more chromosomes..
when parts of chromosomes are broken off and lost during mitosis the results is a chromosomal mutation
Mutation, independent orientation of chromosomes in meiotic prophase, crossing over of genetic material in prophase of meiosis and random fertilization of and female gametes.
Gene Mutation or just mutation.
yes......dimples are considered a mutation which means that someone can get dimples even if the parents don't have that trait or gene.
There is a 50% chance of a child having dimples if one parent has them and a 75% chance if the two parents have them. A child can also have them as the result of a genetic mutation even if neither parent has dimples.

Chromosomal mutation
This is because mutations occur in x chromosomes. The male, who has "xy" sex chromosomes, will have the mutation if it is present in the x chromosome. Females, there is a smaller chance because there are two "xx" chromosomes, which reduces the chance that the mutation will be present.
Aneuploidy mutation causes a change in the number of chromosomes. Aneuploidy occurs during cell division when the chromosomes do not separate properly resulting in a change in the number of chromosomes.
