We like to address clarifications or corrections in our videos in the pinned comments. Pinky accidentally said "coefficients" at 2:10 when she should have said "exponents." These are exponents as shown in how the sex-linked trait was written at that time stamp. We greatly appreciate the individual who let us know this was in the video! :D

I love it! And - gotta share real quick - when the nurse at the hospital told us that our youngest daughter's bloodtype was O negative, I exclaimed (with a large amount of enthusiasm), "That means that we know the genotype for both of our blood types!!" and then explained to my husband how this was proof that he (being O positive) was heterozygous for the Rh factor, and I (being B negative) was heterozygous for the B allele. The nurse looked at us a little strangely and said something about O neg being the universal donor -- and we were like, "Yes, yes, that's very cool too. But we're basking the joy of a genotype/phenotype discovery here!"

I really enjoy showing your videos to my Biology classes. After watching this video I felt that it was important to address the family structures that are depicted i this video - in hopes to try and normalize every type of family. In addition to pedigrees - I asked the students how might they change this video to better accommodate all families (some with two moms or dads, some with one grandma etc...) with a pedigree chart. It led to a wonderful class discussion

My dad is over 50 and had never heard “pedigree” in the context of science. Having been in the middle of this video (and watching it for the second or third time) I explained to the best of my ability (my HS Bio class was interrupted by the COVID Pandemic two years ago) and provided the example of my strawberry-blonde hair. I am not the only person in my family who has this hair color-dad was pretty redheaded as a child-and once I had said it, it made me wonder who else in my family has, or had, this trait. I’m pretty certain it’s a recessive trait, since my mother and my maternal grandparents both have/had dark hair, but my dad and I both have lighter hair. This would mean that my mother is a carrier and someone in her family must have had the trait. All of my aunts and uncles, even the ones who are not biologically related to me, have dark hair, but some of my cousins have light strawberry-blonde hair like me. It would be interesting to create a pedigree of my living relatives and figure out where the gene came from in the three or four generations I can actually track. Another good trait to track would be my blue eyes since many of my family members also have blue eyes, including my Dad and maternal Grandpa. (My father was raised by his grandparents, so he would know more about my paternal great-grandparents than my paternal grandparents. Unfortunately most of my dad’s family have crossed beyond the veil into the realm of spirits... in other words they’ve died.) Excuse the novel of a comment.
