Can Lucy and Maria be biological twins?
Needless to say, Lucy and Maria are not identical twins they are dizygotic twins. This usually happens when two fertilized eggs are implanted in the uterus wall at the same time. When two eggs are independently fertilized by two different sperm cells, fraternal twins result.
Why do Lucy and Maria look so different?
Non-identical twins come from separate eggs, so inherit different genes. The girls’ half-Jamaican mother carries genes for both white and black skin. By chance, Lucy will have inherited genes for white skin and Maria will have genes that code for black skin.

Identical twins are also known as monozygotic twins. They result from the fertilization of a single egg that splits in two. Identical twins share all of their genes and are always of the same sex. In contrast, fraternal, or dizygotic, twins result from the fertilization of two separate eggs during the same pregnancy.
Can you be identical twins and not look alike?

Can 2 sperms enter an egg?
Occasionally, two sperm are known to fertilize a single egg; this ‘double fertilization’ is thought to happen in about 1% of human conceptions. An embryo created this way doesn’t usually survive, but a few cases are known to have made it these children are chimaeras of cells with X and Y chromosomes.
