If brown eye color is a dominant trait Andy blue eye color is a recessive trait what can be determined about the color of Carla's eye?

If brown eye color is a dominant trait and blue eye color is recessive, then Carla's eye color can be either brown or blue. If she has at least one allele for brown eyes, she will have brown eyes. If she inherits two recessive alleles for blue eyes, then she will have blue eyes. Without additional information about her parents' genotypes, we cannot definitively determine Carla's eye color.


Is brown the dominant eye color?

No, blue is. Blue is a baby's eye color and then they change to whatever color after about one month.


Why Several genes control human eye color. Because of this eye color shows a continuous variation from very dark brown to green to blue. What is this an example of?

Eye color is not an example of polygenetic traits. Skin color is. Eye color is rather simple as far as genetics go (in humans). Brown (B) is dominate and blue (b) is recessive. A person with blue eyes has to have to have both genes for the color blue (bb). A person with brown eye color can has both genes for brown (BB) or one for brown and one for blue (Bb). The blue is not expressed in this case with Bb. Some people have hazel eyes but this is a variation of the blue color.


What are the alleles of a brown eyed men and blue eye women that have a blue eye child?

the fathers gene is stronger


If Jon Gosselin has green eyes and Kate has blue eyes how did all eight children have brown eyes?

Kate Gosselin has brown eyes. Biologically speaking, brown is a dominant color. Jon and Kate must both have brown eyed genes in them. If I remember correctly, a recessive eye color like blue or green has a 1 in 4 chance of occurring in the offspring on average.
