Q7 (e) The fish with favourable alleles / genetic sequences survive different environment / conditions / food / predators / selection pressures / other appropriate (on either side of isthmus). 1 mark

There was also a slip in m/c q 17 where reptile appears as "retile" in one of the incorrect options.
