Question

Predict how many double helical molecules of dna will be present in the gametes of the fruit fly, drosophila, a diploid organism that has eight replicated chromosomes in each cell that enters meiosis. see section 13.1 ( page 273) .

Answer 1

The answer is four double-helical molecules of DNA, which match up to four unreplicated chromosomes. In addition, for fruit fly gametes the haploid number is 4 in which can be written as N = 4. The meiosis is a procedure in which the amount of chromosomes per cell is cut in partial in excess of the parting of homologous chromosomes in a diploid cell.
