Detailed explanation-1: -Which statement describes how cloning is different from selective breeding? Cloning eliminates recessive alleles from a genome.
Detailed explanation-2: -Which best describes a difference between cloning plants and selectively breeding plants? Cloning requires two parents and selective breeding requires one parent.
Detailed explanation-3: -What’s the difference? When scientists clone an organism, they are making an exact genetic copy of the whole organism, as described above. When scientists clone a gene, they isolate and make exact copies of just one of an organism’s genes.
Detailed explanation-4: -The primary difference between molecular and reproductive cloning is that molecular cloning seeks to produce many copies of a single molecule, like a sequence of DNA, whereas reproductive cloning seeks to make an identical copy of an entire organism.
Detailed explanation-5: -Clones contain identical sets of genetic material in the nucleus-the compartment that contains the chromosomes-of every cell in their bodies. Thus, cells from two clones have the same DNA and the same genes in their nuclei.
