Yes, but not monozygotic twins.
There are cases where a woman was impregnated by two (or more?) men very close in time to each other, and two ova were fertilized by different men. In that case black and white twins are quite possible.

No, faternal twins are created from two different egg cells. They have some similar genetic information however. Indentical twins on the other hand, would have identical fingerprints since they are created within one egg cell.
No, not always. The offspring can be white, black, black and white or shades of both.
The black and white combination animals that might appear in a zoo listed as follows; * The Zebra * The Giant Panda * The Skunk * The Badger * The Polar Bear * The Colobus Monkey * The Penguin
No. In order for them to be identical they needed to start off as the same cell and divide so at first their DNA is identical meaning they have the same sex. During development slight changes may occur but the sex always stays the same. Boy-girl twins are always two different cells meaning that they are not identical. The term for boy-girl twins is furturnal. You can however have boy-boy twins and girl-girl twins that are not identical and they are also called furternal. So basically, identical twins start off as one cell that divides and furternal are two individual cells. There is polar body twinning, that's when the egg splits before fertilization, and that can cause a male and a female. This is called semi identical twins or half twins. They share 75% of their genetic markers.
How do fraternal twins form? Answer one egg from each ovary is fertilized.
Fraternal twins are more popular.
Another name for fraternal twins is dizygotic twins.
There is no precise percentage of fraternal or identical twins but it is estimated that 2/3 of all twins are fraternal where as 1/3 of twins are identical.
identical twins are single egg twins. fraternal twins a two egg twins. fraternal
Fraternal twins can be the same sex or opposite sexes. It doesn't matter.
Female twins that are not identical are called fraternal twins. Fraternal twins occur when two separate eggs are fertilized by two separate sperm. Maternal twins refer to twins that share the same mother but can include both identical and fraternal twins.
Yes, fraternal twins are perfectly normal.
fraternal twins have two different chromosomes
Fraternal twins are two siblings that have the same birth day, but do not look identical.
The girl and boy twins are fraternal, meaning they are not identical.
