Answer:
If a diploid cell in G2 has 66 DNA double helices, it must have 33 pairs of homologous chromosomes
Explanation:
Diploid cells (2n) are those that have two chromosomal sets, that is, the chromosomes in these cells are arranged in pairs. Each pair has the same chromosomes (regarding size and shape) and the same genes. These equal chromosomes are called homologues. In this case, if a diploid cell has 66 chromosomes, we can conclude that these chromosomes are grouped into 33 equal pairs of homologous chromosomes.
