Answer: I would say its probably A I'm not sure but that might be it
Explanation:
Answer:
DNA
Explanation:
Deoxyribonucleic acid or DNA is defined as the genetic material in all the living organisms responsible for all the genetic activities in an organism.
DNA carries genetic instructions that are inherited from one generation to another generation. The DNA comprises of genes having specific genetic code that encodes the sequence of amino acid residues in proteins. DNA undergoes the process of replication and form several copies of it which are passed on to next generation.
Hence, the correct answer is "DNA".

Answer:
Mutations and gene recombination
Explanation:
Mutations are changes in DNA sequence that can create genetic variation within the population and thus are the ultimate source of new alleles . Mutations are important for evolution because of their ability to form a new genetic variant (allele) that can be spread to the offspring. If a new variant of a trait formed by a mutation is advantageous and helps the organism to survive and reproduce, it is going to be favourable by natural selection. That variation will more likely be passed to the next generation and remain over time.
Genetic recombination is a process that occurs during meiosis between homologous chromosomes and it involves exchange of genetic material between them. As a result, offspring inherits reshuffled alleles different than their parents.
Another sources of genetic variation are random mating and random fertilization.
