IMO the big problem with this is for old APKs that were created before this new developer registration requirement- you won't be able to install them at all without rooting or using a different vanilla Android version.
It prohibits developers from creating apps and maintaining their anonymity but it also prevents scammers from anonymously stealing people's money with fake apps.
Will be a big problem if their developer registration process is difficult or used as a restriction somehow to govern who can register.
If you have one person with recessive genes and one person with dominant genes, then the baby will have the dominant gene. So if the grandparents were cousins both with recessive genes it wouldn't matter, as far as I know.

There is a for-profit medical clinic near me where they told the workers that " we're all just really cool and we love our jobs so we don't take breaks" - they didn't allow workers to take breaks as required by law so I created pamphlets about how to report and get compensation for wage theft and I passed them out on all the cars outside the clinic.
You can get a 66% chance of being right if you turn on a switch and check the room. If the light is off you guess between the other two.
For example, you are going to test switch 1 and if it is off you guess switch 2.
Reminds me of the Monty Hall problem except in that problem the game show host has an action to take which effects the odds.
