There's the biological answer and there's the physics answer.
Biologically, yes, it's determined by your genes. Interestingly, the mutation that originally caused blue eyes occurred only about 10,000 years ago. Prior to that, all humans had brown eyes. Everyone who now has blue eyes is a descendant of that one person with the mutation.
The physics answer is that the blue color is caused by Rayleigh scattering. In other words, blue eyes are blue for the same reason that the sky is blue.
Blue eyes and brown eyes are caused by different genes.
Blue eyes are caused by a specific gene.
blue
You would say "Have your parents got blue eyes?" or "Do your parents have blue eyes?"
You have a better chance of brown, because brown is dominant. If one of your girfriend's parents have blue eyes you have a The your girlfriend is a carrier of the recessive blue eyes gene and there is a 50% chance that your child will have blue eyes. If neither of her parents had blue eyes but one of their parents had blue eyes there is a 25% chance your child will have blue eyes. But statistics do not generally apply perfectly to real life, because life is fairly random. So it's better to say your chances SHOULD be 50% of having a child with blue eyes if one of your girlfriends parents have blue eyes, and your chances SHOULD be 25% etc.....
Blue eyes - a recessive trait.
It is possible for a child with a brown-eyed parent and a green-eyed parent to have blue eyes if there is the trait for blue eyes in the child's genetics. Such as a grandparent with blue eyes.

Blue eyes white dragon. Here's why 1. Blue eyes white dragon has a better fusion, which is blue eyes ultimate dragon, and then, blue eyes ultimate dragon has another fusion with black luster soldier to make the 5000+ATK/DEF. All red eyes black dragon has is to fuse with summoned skull and make B. Skull Dragon with 3200 ATK and 2500 DEF, in addition to Meteor B. Dragon, which also is not as powerful as blue eyes ultimate dragon. 2. The two both require two tributes, but blue eyes white dragon has 3000 ATK and 2500 DEF; Red Eyes B. Dragon only has 2400 ATK and 2000 DEF. Neither have an effect, which makes Blue Eyes White Dragon better in attack and defense. There is one thing that makes red eyes black dragon unique red eyes black dragon has many relatives: red eyes metal dragon red eyes zombie dragon red eyes b. chick red eyes darkness metal dragon B. Skull Dragon Meteor B. Dragon Blue eyes white dragon has: Blue Eyes Ultimate Dragon Dragon Master Knight Blue Eyes Shining Dragon Blue Eyed Silver Zombie Blue Eyes Toon Dragon This is my opinion.

Blue eyes come with some white cats, and cats with points like Siamese and Ragdoll. They also sometimes come with the silvering gene, which makes silver tabbies. Blue eyes are rare in cats of other colours. White cats with blue eyes are prone to deafness; not all of them, but many of them.
