Final answer:
In a heteroduplex during meiosis, one daughter cell having original information refers to semi-conservative DNA replication, where each daughter DNA molecule retains one parental DNA strand coupled with a new complementary strand.
Step-by-step explanation:
In the context of heteroduplexes during meiosis and DNA replication, when a cell divides, each daughter cell receives genetic information from the parent cell. Specifically for your question, in a heteroduplex, if one daughter cell has original information, it implies that DNA replication is semi-conservative. That is, one strand of the parent DNA double helix is retained in each new DNA molecule, paired with a newly synthesized complementary strand. This means that after replication, the daughter cells have one original and one new strand of DNA.
DNA replication is crucial during cell reproduction because it ensures that each of the two daughter cells receive a complete set of genetic information, crucial for the maintenance of genetic continuity. The genetic content of the two daughter cells in prophase II of meiosis is haploid with one copy of each gene, signifying each cell has half the number of chromosomes of a diploid cell and one complete set of genetic instructions.
