Scientists have created mice with two biologically male parents for the first time — a significant milestone in reproductive biology.
Old female mice had more PLP1 in the hippocampus than old male mice, suggesting that the extra PLP1 from the second X chromosome had made a difference. To test whether PLP1 could explain the ...
