What Would You Do?
Reproductive Scientists were recently able to manipulate cells in order to create a mouse embryo from two genetic fathers. First, the scientists created an iPS stem cell line from the cells of a male (XY) mouse fetus. Certain cells of this line randomly lost their Y chromosome, transforming into XO cells.
Next, scientists injected the XO cells into embryos from donor female mice and transplanted these cells into surrogate mouse moms. The resulting mice born were then mated with other males. Their offspring, contained genetic material that only came from the two fathers.
