Look at the reference here to John Sanford’s work: Sanford and Carter: Allele Frequencies and a YEC Adam and Eve.
Though I hestate to include a reference to AIG, look what they write about it here:
Shouldn’t Eve Have Been a Clone of Adam? | Answers in Genesis which is connected to the Designed Diversity hypothesis: Getting Enough Genetic Diversity | Answers in Genesis.
Basically no YEC scientist I know of claims Adam and Eve were clones, and may have been protesting that their model is being misrepresented. I agree with them here. There is no reason to misrepresent them any way. The genetic evidence rules out their position either way. There is no defensible reason to strawman them.
