This is very simple people carry genes from ALL their ancestors that’s why all humans are related.

Let’s use a deck of cards to represent the parents dna. For simplicity I’m starting from the grandparents.

Assuming Kushina is a pure Uzumaki = 100% 26 chromosome pairs = 52(cards) Same with minato assumption he was 100% Namikaze = 52 cards

Since children receive 26 from each parent naruto would be = 50% Uzumaki, 50% Namikaze.

Now if minato and Kushina had other children it would be like someone taking both their full decks of cards (52) and shuffling it then picking a random 26 cards again. This means that even though it is highly unlikely the siblings all receive the same 26 from each parent, they will in fact receive some genes which are similar hence why siblings are related. Both siblings will still represent 50% of each parent and approximately 50% of each other.

So in the boruto’s case he would be 50% hyuga, 25% Namikaze, 25% Uzumaki. Since both Hinata’s parents were Hyūga.

Sarada would be 50% Uchiha 25% Haruno and 25% of whatever Sakura mom is assuming she is not Haruno.

A offspring of boruto and Sarada would be 25% hyuga, 25% uchia, 12.5% Uzumaki, 12.5% Namikaze, 12.5% Haruno and 12.5% of whatever Sakura mother is.
