That made me chuckle.
But it's possible for siblings not to share any genetic material right?
A brother and a sister would obviously get different genes from their father and presumably there would be a 50/50 chance of them getting different genes from their mother.
There's four unique prototypes of children any two people can produce together.
- caseymarquis 3y agoI thought it was more like 2^23 unique prototypes?
- darkerside 3y agoFour prototypes?
- danwills 3y agoGamete cells get a random half of all genes from each parent so there's about 2 unique possible 'sets' from each parent, and 2*2=4. However because it's random I think you can only say there are 4 distinct completely unique possibilities in theory, but it would be very unlikely for that to actually happen in practice.
- darkerside 3y agoAhh, as in fully exclusive sets of genes
- diroussel 3y agoEach parent supplies half the genetic material. But each sperm and each egg have a randomly different set of one half of each chromosomes. So if you have 10 children chances are they each have a unique set of chromosomes.
- rand0mx1 3y agoProbably genotype. Isn't it
- fsckboy 3y ago>Four prototypes? gp said four unique prototypes
- harry_ord 3y ago> But it's possible for siblings not to share any genetic material right? Kinda but the mother always provides the mitochondria.
- CSMastermind 3y agoI think that's an area of open research: https://www.pnas.org/doi/full/10.1073/pnas.1810946115 https://www.pnas.org/doi/full/10.1073/pnas.1810946115 But yes, that's a good distinction I should have made!
- harry_ord 3y agoOh that's cool. Now I have something new to read thanks.
