Can a baby have 2 fathers DNA?

Can a baby be made from 2 sperm?
The researchers say it appears that after fertilization, the DNA from the egg and two sperm divided, then got divvied up to create three embryos. Two of the these had enough egg DNA and sperm DNA to make viable embryos. The remaining embryo, with only sperm DNA, was not viable.
Can a person have 2 different DNA?
Some people’s bodies do indeed contain two sets of DNA. A person who has more than one set of DNA is a chimera, and the condition is called chimerism. … But you don’t have to have had a vanishing twin to be a chimera. Regular fraternal twins can also have the condition.
Can a baby be made without sperm?

What happens if more than one sperm enters the egg?
To ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. … If this mechanism fails, multiple sperm can fuse with the egg, resulting in polyspermy. The resulting embryo is not genetically viable and dies within a few days.
