My understanding is that human-neanderthal interbreeding rarely resulted in viable offspring (though some did, and is where blonde/ginger hair and blue eyes come from in modern humans).

Is that similar here? Are there traits in modern goats or sheep that came from the other?

Blue eyes is a more recent mutation [1]. Blonde hair has appeared independently several times [2].

As a Scot I might be a bit touchy about this (Scots have the highest proportion of redheads and I carry the gene even though my hair and eyes are very dark):

"A DNA study has concluded that some Neanderthals also had red hair, although the mutation responsible for this differs from that which causes red hair in modern humans."

...where do you have that "understanding" from?! Are there any actual information about the 'Homo sapiens sapiens' <-> 'Homo sapiens neanderthalensis' contact and relationship or are you just spreading someone's wild guesses?

Most Europeans have Neanderthal genes.
