However, there are well documented, genotype-confirmed cases of goat-sheep hybridization.
Sheep and goats both belong to taxonomic Family 'Bovidae', with sheep in genus 'Ovis' and goats in genus 'Capra'. The two are often raised together on farms.
And very, very rarely, they can interbreed to produce hybrids called GEEP, as in Butterfly (shown), born 2014.

I want to go into research
Preferably something in natural sciences, soil sciences, ecology.
I have a Bach degree in MCD biology and experience as a cytogenetic lab technician + EHS officer.
Where do I look, and what are my prospects?

Hey, women in science roll call! We’re not invisible and we can’t be erased. RT if you’re a woman in science!
Walking in to NASA’s JPL today as a woman in science leadership felt almost like a protest. They can take us off the webpages and the walls, but we will still be here, absolutely crushing it, and supporting our community while we do it.
