Does a mom or dad ever give more DNA to a baby than the other parent? Why?​
andreyandreev [35.5K]

The mother actually gives more DNA to a baby more than the father because of the little organelles, aka the mitochondria that live inside your cells are only to be received from your mother.

But in DNA, it can vary who's side you can get more of, and in some rare cases, equally. This is because dominant genes carry out around 75% of the time and genes that are recessive can carry out 25% of the time, depending on the genetics of both the mother and the father. Example, brown eyes are a dominant gene over blue eyes, so there is a 75% chance that the baby will have brown eyes and a 25% chance that the baby has blue eyes if one parent has the brown eye gene and one has the blue eye gene.

I hope this helped!! :D
