What happens after step (iv) in the diagram shown below? DNA replication in the gametes will restore the diploid chromosome number.
Fertilization of the gametes will restore the diploid chromosome number.
The haploid daughter cells will undergo meiosis II to produce gametes.
The haploid gametes will grow, replicate, and then undergo mitosis.

its b

explanation:

there is no change

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."

it's c. (to reduce the greenhouse effect/carbon gasses)
