I've shared this picture on my blog before, but it's been a few years so I thought I would share it again.
Not everyone can say they have a picture of their chromosomes so I think it's pretty neat that Kayla has a picture to show what hers look like.
I have been emailing this picture to Kayla's teachers the past 3 years so they can show it on the Smartboard when I come in to talk to the class about Kayla and Down syndrome.
This year Kayla is going to tell the class that she has 47 chromosomes and I, and the rest of the class, have 46.
I think this visual is helpful for her classmates to see what chromosomes look like ... and pointing out the extra one on the 21st pair is what makes Kayla have Down syndrome.
I will tell them that people with Down syndrome have been around as long as humans have been on this Earth.
Most people are born with 46 chromosomes but some people are born with 47. Sometimes that extra one is on the 21st pair, sometimes it's on the 13th or 18th. Some people are born with deletions and have a missing one from a chromosome pair.
It's the diversity of humankind.
Having an extra chromosome is just the way Kayla was born and that's ok.
