I have identical twins. One of my sons has blue eyes and the other has one blue and one blue/brown eye. It's called "sectoral heterchromina", possibly caused by a genetic mutation or virus that occured whilst they were in the womb. So it is possible for monozygotic twins to have different colour eyes. .

No, they are ferternal. They have different colored eyes and one used to be shorter then the other. If you get any of their old movies you can tell. Mary-Kate usually has shorter hair then ashley, but that doesn't make them ferternal.

Both of her eyes are light brown. However it looks like the left has a slightly darker iris, meaning she had mild heterochromia (different coloured eyes). This is a common condition in twins, and she has a twin sister.

homozygous is a word used to describe when a cell has two identical copies of a gene different varieties of a gene are called alleles (e.g blue eyes allele, brown eyes allele both are genes give eyes a colour but the colour they give is different If a person were to inherit two alleles for brown eyes, i.e one from each parent then they would be Homozygous for brown eyes i.e one from each parent. on blue one brown they would be Heterozygous for eye colour.
