finger Print

What makes each of us so unique?  Families pass down physical traits but finger prints are one item that are unique. Partially inherited, yet unique, this experiment and report will let you know if your fingerprints are inherited.Humans have friction ridge skin on their hands and feet. This skin is on the ridges and dips that cover the pads of your finger and toes and it helps you grip things. Not one human has the same friction ridge skin pattern, not even twins!  It stays the same throughout your life. The only way friction ridge skin can change is by permanent damage such as a scar. There are three main fingerprint patterns these are called: 1. Loop;  2. Whorl;  3. Arch.The type of fingerprint is determined while the baby is a fetus.  Each fetus’ fingers have a pad called a volar.  The volar pads stop growing around ten weeks but the hands still grow.  Because of this the hand absorbs the pad. Signs of ridges appear on the pad.  If the ridges appear  when the fetus has a high volar pad (not absorbed much) then whorl pattern appears.  When the volar pad is an intermediate volar pad, a loop pattern is formed  The low volar pad (when the pad is almost completely absorbed) develops into an arch pattern.  It is important to note that each finger can be different.  A thumb can have a loop pattern while another finger can have a whorl pattern because it was in a different volar stage. The questions I’m going to ask are: 1. Are Noah and Lauren’s fingerprints similar (siblings fingerprints)? 2. Are mother and child fingerprints similar? 3. Are Lauren’s fingerprints more like her moms or dads? (female-female or female-male)   Question #1 answer:Brother and sister, Lauren and Noah, both have the loop pattern thumb print.  Under the magnifying glass it is obvious that the friction ridge pattern is different, especially in the center of the print.   Question #2 answer:Again, the similarities extended beyond siblings to the mother. In several test subjects the girls appeared to have stronger similarities to the mothers than the boys. What I have researched It looks like the mother and daughter have a stronger relationship than the son and the mother. The sons fingerprint looks more like the fathers than the mothers it has wider ridges                                                                                    Question #3 answer: Lauren’s thumbprint resembles that of her mother’s but the friction ridges are different, which make her unique! In relation to her Dad, Lauren’s thumbprint                                                  .In conclusion, looking through the loop of the magnifying glass, Lauren’s fingerprint looks more like her mom’s it has a loop. In the center of Lauren’s fingerprint it looks like it has a lowercase I from my observations it looks like Lauren and her Mother both has a loop. In the middle of both their fingerprints are what looks like a lowercase I.  In summary, based on written research and the tests conducted by myself, there is an inherited  factor in fingerprints.  Studies on identical twins indicate the primary ridge appearance and volar pad absorbing into the hands, genetically influence the pattern type of fingerprints. Fingerprints are NOT inherited.
