The continuation of life depends of both what and what

The continuation of life depends on both sexual and asexual reproduction.

Reproduction is a process where an organism gives rise to another organism, often called as "offspring". Its a process of increasing the population of any species on Earth. There are two types of reproduction process-

1. Asexual- where exact copies of parent organism are formed, also only single parent is involved.

2. Sexual- Two parents of opposite sexes are involved, offsprings are not identical to parents. There is scope of variation in sexual reproduction.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
