Our neighbor and us both have different eye color but parents have the same? click 4 details?

my nextdoor neighbor(bro $ sis) both have brown eyes and me and my bro both have green eyes. their spanish. we are white. both of our dads have brown eyes and both of our moms have green eyes. what's up with that?Our neighbor and us both have different eye color but parents have the same? click 4 details?
genetics is the study of heredity and variation. most traits are inherited from the parents; sometimes it's the same as the father's, sometimes it's the same as the mother's, other times it's a combination of both and in some cases, the traits inherited can not be seen in any of the parents.





let's try to find out the probabilities or chances of inheriting the eye color trait... i think brown eye color is a dominant trait (B), and green eye color is probably recessive (b) so:





if the father (or male/m) is heterozygous dominant for the trait (Bb) and the mother (or female/f) is most probably homozygous recessive (bb) then...


m\f b b


B Bb Bb


b bb bb


-----------


2 Bb : 2 bb


or 50% chance of brown eyes and 50% chance of green eyes





but if the father (or male/m) is homoozygous dominant for the trait (BB) and the mother (or female/f) is most probably homozygous recessive (bb) then...


m\f b b


B Bb Bb


B Bb Bb


------------


4 Bb


or 100% chance of brown eyesOur neighbor and us both have different eye color but parents have the same? click 4 details?
Brown and blue are dominant alleals and hazel is recessive. Green is heterozygous Brown and Blue. Your green eye pigment is from your moms moms blue trait mixing with your dads brown trait.

ur dad carries traits for brown genes n ur mom carries traits for green genes.in ur case green genes dominate over the recessive brown genes. hence u n ur brother hv green eyes but in ur neughbours case brown gene seems to be dominant over green. we learn all this in genetics. ull find many couples wid same eye colour as ur parents..
ok, brown is dominant to green.





your dad`s genes is Bb (B representing Brown and b representing green)





Your mom`s genes is bb





Bb if married with bb will have 2 possibilities for their child:


50% Bb (brown)


50% bb (green)





your neighbour`s dad genes BB and his wife is bb


so the possibilities of their child are 100% Bb


which mean all of their children must be browned eyes.





BB = brown


Bb = brown


bb = green
i think different races, like Hispanic and African, who have darker skin colors, the brown eyes and darker skin are always dominant. And with white people blue or green eyes are dominant.
The wonderful world of genetics. Just because your parents' eyes are their current color doesn't mean that they do not carry the genes for other eye colors. It just happened that way. Once you get into Biology you'll see how this happened.
yes it is truly all a play of your family genes.u know chromosomes is important cell organelle which contain genes which determines the hereditary characters.the same case with u.


we get different characteristics from oUr parents or grandparents or even from our forefathers. in your case u and ur bother heredited eye color from your mom whereas your neighbors from their father.


your parent must have heredited eye color from their parent or others. same way ur neighbors parents have herideted from their parents.


its not because of any relation between u and ur neighbour. they hereditate from their family and u from yours family. thats all.
it is due to your grand father and grandmother genes
