Guess my Mom and I's ages, and are we equal?

Some background (not sure if this was the right place to post/ask but this is a throwaway account so YOLO):

It was my birthday yesterday. Shared some pics of me and my mom with my college friends (live out of state, never met my mom) and they refused to believe she was my mom until I literally sent them baby pics. Now, I'm pretty used to people saying she looks young and my dad gets asked about his 3 daughters (he only has 2) all the time but this is a new low for me. Pretty soon Im going to start to look older and what really irks me is that my mom doesn't believe me (or anyone) and thinks they're all just being nice. So strangers.....how old do we look and do we look alike (this is mostly for my Dad because he claims I got all my "good genes" from him)?
