Which of the following is beleived to create new alleles or genetic traits in an organism
a. crossing over durning meiosis 1
b. natural selection
c. random mutations
d. fertilization

Its C

Explanation:

DNA mutations occur in germ cells – cells destined to become eggs or sperm. In this case, the DNA mutation is copied into every new cell of the growing embryo following fertilisation. In this way, new DNA variants are passed on to the next generation. If the mutation affects a gene, it will result in a new version of that gene – a new allele.
