The full effect of liposuction is seen six to 12 weeks after the procedure is performed. After the procedure, the area is bandaged and the patient must wear a compression garment for one to two weeks. Pain and bruising may last up to two weeks, and swelling may last for two weeks to two months.
This leads to lots of chromosome mixing. Mixing lowers the chances of siblings inheriting the same big chunks of DNA. So on average, two siblings will share about 50% of their DNA. In rare cases where a brother and a sister share more than 50%, they will be more similar than two sisters.
Here is my full sister and how much DNA I share with her as well as the number of segments that we have in common. Siblings are expected to share about 50% of their DNA --- my sister and I share slightly more than expected, just by random chance. Getting your siblings tested at 23andme is very useful because they will have DNA (and relatives along that DNA) that you do not have.
