This explains many things. LOL!
I grew up watching my aunt (my second mother) studying her Bachelor of Education degree in Biology, at the Universidad de Oriente (UDO), Núcleo Sucre, Sucre State, Venezuela.

I remember when she did his experiments with those Drosophila melanogaster mosquitoes.
She used glass jars with "agar". There the "fruit mosquitoes" would reproduce.
She used gauze plugs that he impregnated with "ether" to put the mosquitoes to sleep and then she had to count the males and the females.
All this to demonstrate Mendel's laws of Genetic Inheritance.

I was a child, but I remember it clearly.

There are also educators and health professionals in my family. My mother is a graduate nurse, I have uncle doctors ...

Brother, it is a pleasure and an honor that we are friends.
