Why are female clones more often produced?

Question

As a student of biology when ever I come by artificial cloning, I always find examples of females being cloned - Dolly the sheep, CopyCat, Daisy, etc. The only male I could see was Fibro mouse and a few more. What is the reason behind this? Is the male genome more difficult to be cloned? I am specifically looking for genetic reasons or other complications.

Answer 1

When scientists clone an animal, their main question, besides from asking if cloning is possible, is if the animal can give birth to a viable offspring. Hence, this is why all mammal cloning experiments involve females.
