The Official The Sims 4 100 Baby Challenge [UPDATED ON DEC 29, 2018]

I have a couple questions:

1) Is a 2nd generation matriarch allowed to be impregnated by a man who impregnated the 1st matriarch? Like, lets say Male A impregnated Matriarch A. Matriarch A grows to be an elder and Matriarch B takes over. Can Matriarch B be impregnated by Male A as long as he's not her father?

2) Can we use same-sex pregnancy mods? (this is actually a question for someone else. I told her we can't but she was like 'you should ask')
