Final answer:
Each daughter cell at the end of meiosis II will have 37 chromosomes and 37 double-helical molecules of DNA.
Step-by-step explanation:
In meiosis II, each daughter cell receives half the number of chromosomes and half the number of double-helical molecules of DNA as the parent cell. Since polar bears have 74 chromosomes in their diploid cells, at the end of meiosis II, each daughter cell will have 37 chromosomes and 37 double-helical molecules of DNA.
