Yes in fact colorblindness is related to genetics.
Colorblindness is a sex (gender) linked disorder. In order to find out how colorblindness is inherited you must first know a little bit about sex linked genes.
Every person has 2 sets of gene for each trait (one set comes from your mom and one set comes from your dad) except when it comes down to genes found on your 22 chromosome ( or sex chromosomes)
The X sex chromosome is bigger than the Y chromosome and thus holds a few extra genes on it. In females because they have two X chromosomes they still have two of every gene. However, in males they only have one X and therefore they only have one set of the genes that are only found on the X chromosome and not the Y.
Colorblindness is one of these genes. It is also a recessive gene found on the X chromosome. Because females have two X's they are not likely to become colorblind. This is because in most cases a female will inherit the gene for colorblindness in one X and a gene for normal vision on the other X. But because males only have one X, if they have the gene for colorblindness they do not have another gene to dominate this one and therefore become colorblind.
In order for a male to become colorblind his mother should be either colorblind or a carrier for colorblindness, as a male gets his X chromosome from his mother.
No, having blue eyes is not considered a birth defect. Eye color is determined by genetics, and blue eyes simply indicate a lack of melanin in the iris. It is a natural variation in human eye color and is not harmful or problematic in any way.
Ordinary eyecolor? No. Blue eyes result from having two copies of the blue eye color gene, one from each parent. Since the blue-eye gene is recessive, one MUST have two copies. Someone with one blue-eye gene and one brown-eye gene will be brown-eyed.
Colored eyes are not a genetic defect. A defect would be if the eyes functioned poorly. Scientists now say that all blue eyed people had a common ancestor that was the first to have blue eyes about 6,000 to 10,000 years ago.
