 You cut some sheep DNA and some plasmid DNA with the same restriction enzyme. The plasmid contains an  AmpR gene and a  lacZ gene. You mix together the fragments of sheep DNA and the linearized plasmid. You transform bacteria with your mixture, and plate the bacterial cells on growth media containing the antibiotic ampicillin and X-gal (the substrate of beta-galactosidase). You need to pick some bacterial colonies that contain recombinant plasmids. Which colonies do you choose?

Anury is the absence or abbreviation of the tail in sheep (and also other animals). It is inherited in an autosomal dominant fashion. A ram with anury is mated to a ewe with a normal tail. The ram’s father had anury, his mother did not. What is the probability that the ram and ewe will produce a lamb with anury? (ram = male; ewe = female)
