Question 10 (2 points) the result of the replication of a dna molecule resules in identical copie(s) of dna which are to the original parental dna molecule.

...which are identical to the original parental DNA molecule.

Explanation:

Before a cell will divide the DNA it contains must first replicate to ensure that the resulting cells from the division will contain the same DNA for it to function similarly as well. Replication of DNA is a semi-conservative because the resulting DNA molecule will be half old or half new, where one strand is from the parent DNA and the other is a newly formed strand.

The newly formed strand of each side will be identical to the former complementary strand before it unzipped.

explanation:

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
