Wild hamsters (Hamsteris silvestris) and common mice (Mus musculus) are diploid.

Question

Wild hamsters (Hamsteris silvestris) and common mice (Mus musculus) are diploid. In wild hamsters 2n = 38, while in common mice 2n = 40. Based on this information, we can conclude that if we were to compare G2 cells isolated from the two rodents, wild hamster cells have

      
fewer DNA molecules than common mouse cells

      
fewer genes than common mouse cells

      
less DNA than common mouse cells
      
smaller genomes than common mouse cells

      
lower genetic diversity than common mouse cells

Explanation / Answer

G2 phase is a post synthesis phase i.e. DNA just double of its content at initially of this phase. Wild hamster have 2n = 38 and common mice 2n = 40. Basically if we are looking from this information so the more no of diploid chromosome have larger genome. But we do not go further about DNA content, no of genes and genetic diversity because this is not enough information. It can be known after analyzing the genome. So the correct answer is

Smaller genomes than common mouse cells
