Could I genetically change my appearance in such a way that my children would resemble my new appearance?
Wow how strange...accept how God made you!
Don't think so....
You could change your resemblance genetically, to change the appearance of your children. However, this is not advisable since it may bring complications in your offspring. This may bring problems in skin color change and also a short life span.
No. You cant duplicate after alterations. Makes no sense. What are your motives?
Change yourself and when u have kids change them
