Question

If one parent has brown eyes and the other has blue whats the percent that the child will have blue eyes

Answer 1

The percentage chance of a child having blue eyes depends on the genetics of the parents, with a 50% chance if the brown-eyed parent is heterozygous for the eye color trait.

Step-by-step explanation:

The prediction of a child's eye color based on parental eye colors involves understanding genetics and the inheritance of traits. Eye color is a polygenic trait, meaning it is determined by multiple genes. While a single Punnett square with only two alleles can predict the inheritance of traits like colorblindness, predicting eye color is more complex.

Nonetheless, if one parent has brown eyes and the other has blue eyes, and assuming brown is the dominant trait and blue is the recessive trait, the probability for the child to have blue eyes depends on whether the brown-eyed parent carries the recessive blue-eyed gene. If the brown-eyed parent is heterozygous, carrying one allele for blue eyes, the child has a 50% chance of having blue eyes. However, if the brown-eyed parent is homozygous for brown eyes, the child will most likely have brown eyes since blue eye color would require two recessive alleles.

Answer 2

This question either isn't complete or it is very open ended. There is so many possibilites. We don't know which is the dominant allele, we don't know if it is hetero or homozygous. If both parents are homozygous then the baby has a zero pecent chance of being clue since it will have incomplete dominance. If the brown eye is dominant then it will have a 100 percent if the browned eye parent is homozygous. But a 50 percent chance if its heterozygous. Same for the blue eyeed parent. Any of these should satisify this question if this is the only part of the question
