This was mentioned to me by my biology teacher - the egg chooses which one fertilises it https://www.news-medical.net/news/20200611/The-egg-decides-which-sperm-fertilizes-it.aspx
P.S. I have also decided to start my own blog! It’s stil just in development and right now is just my previous forum posts, but if you’re interested feel free to check it out here: https://femcurrent2.wordpress.com
The egg should choose better, more baby girls need to be born compared to the XY creatures.
