As a bio major in college, this got me laughing…then thinking…then laughing some more.

I’d forgotten about that mitochondrial DNA bit–where does that DNA come from originally?

A Biologist’s Mother’s Day Song ~ By Adam Cole ~ Lyrics

To make one me you just add Half of mom and half of dad That is what I once believed But I know now that I was wrong I got so much more from you mom Than just half a set of genes I got nutrients and transcription factors and nearly everything that matters plus my prenatal environment (transplacental inheritance) mRNA, mitochondria, That back in the day once belonged to ya (theyre cytoplasmic) and I just want to thank for supplying them

Just like two strands of DNA are spirally entwined Your nature and your nurture are inspiringly combined Scientists remind me and I find that it is true Slightly more than half of everything I am is thanks to you

Mitochondria power my cells and they have DNA as well Transcription factors modulate transcription And since theyre in the cytoplasm The eggs the only one that has em and sperm I guess they dont have much ambition

My sex determination gene means that Im a guy From you I got my X chromosome, from Dad I got my Y X has over a thousand genes, Y has less than 92 Thats why more than half of everything I am is thanks to you

I roomed in your womb for nine whole months and never paid the rent Your glucocorticoids shaped my hypothalmic development I took in your blood and sucked it dry of every nutrient (its gross but true) Sometimes I wonder where the time went (where did it go) Sometimes I wonder where it went

I know Ill never understand all you have done for me (Im not that smart) But since you paid for college Ill get my B. S. degree (bachelor of science) And I have learned its not BS but absolutely true Slightly more than half of everything I am is thanks to you.

“It’s not an even 50/50 split, you get a disproportionate share of your DNA coming from your mom. Really important.”
~ Robert Sapolsky
