Is there any way to guarantee a child with blond hair and blue eyes?

Question

Hey guys! Here's a hypothetical situation: You have been assigned to find two people who will for sure create a blond haired, blue eyed baby if they reproduce. What traits will guarantee this? Can you guarantee this even if one of the people does not have these traits?

Thanks so much!

Answer 1

Both of these traits are controlled by multiple genes. That's why it is not as simple as something that is under the control of only one gene... Mix that with the fact that there are multiple alleles for each trait, and it gets tricky. So, just based on someone's appearance it is not possible to guarantee that someone will be blond and blue eyed. It's complex, but it is possible (though rare) that two blue eyed people will have a brown eyed child... It is also possible that two brown eyed people will have a blue eyed child (if they both have the appropriate recessive genes).

Answer 2

Since both of these traits are recessive, you would need both parents to be blond haired and blue eyed to ensure a blond haired, blue eyed child. If one of the parents didn't have both of these traits, there would be a 25% chance of having a blond haired blue eyed child.

Answer 3

Choose the blondest blue eyed couple you can find.

As soon as you introduce someone with different characteristics, you reduce the probability of blond, blue eyed children

To increase the probability of the child being blond and blue eyed, choose 4 blond blue eyed grand parents too.

And if you can specify the great grand parents, choose them blonde and blue eyed too

Answer 4

No. Because both blue eyes and blond hair are recessive, meaning you need two of each type to get it. So even if one parent has the recessive and the dominante, and the other parent has the both recessive, that one dominate gene can get through and it will win. So the only way to garuntee this is to have two blond haired blue eyed people.

Answer 5

parents would have to be heterozygous blue eyes and blonde haired or homozygous blue eyes and blond haired
heterozygous means they would have to carrie these recessive traits which you can find out maybe if you do by having a family pedigree done
that or both parents would have to exhibit these traits

Answer 6

you need to have a mother with homozygous alleles for blonde hair and blue eyes to reproduce with a father with homozygous alleles for blonde hair and blue eyes

Answer 7

you have to make sure the traits you want are the dominant features but i'm not sure how... you could always try cloning.

Answer 8

i think you can do this through Gene therapies....
