Question

To clone my favorite dog I will need to______________.

		fertilize a dog egg with the sperm from my favorite dog
		DO NOT GRADE
		splice my dog's DNA into another dog's DNA
		combine two haploid cells from my favorite dog
		place the diploid nucleus of the favorite dog into a denucleated dog egg

Which is an example of an ecological reproductive isolating mechanism?

		DO NOT GRADE
		when two populations mate in the same river but at different times of year
		when two populations can mate, but the offspring are sterile
		when ground anole lizards do not climb trees to mate with tree-dwelling anoles
		when two populations of fish are found in unconnected lakes

Answer 1

1. Place the diploid nucleus of the favourite dog into a denucleated dog egg is the answer. Pet cloning is done by taking out the somatic cell from the pet and inserting into the blank oocyte and the electric current is passed to fuse them .

2. When ground anole lizards do not climb trees to mate with tree dwelling anoles. The ecological reproductive isolation states the inability of two species to breed which can otherwise inter breed due to ecological or habitat barrier. Here these two species can interbreed but as their habits are different they are isolated. Again one example is of tiger and lion.
