She measured the amount of DNA in the egg cells of two closely related whiptails, just prior to the first cycle of meiosis. She discovered in this stage, the chromosomes of the asexual checkered whiptail (A. tesselatus) make up two times as much as the sexual Texan spotted whiptail (A. gularis), despite the fact that both types have similarly sized genes. Microscopically, Lutes counted two times the usual number of chromosomes in the egg cells of the checkered whiptails [5,6]. | She measured the amount of DNA in the egg cells of two closely related whiptails, just prior to the first cycle of meiosis.

Surprisingly enough, possessing eight sets of chromosomes instead of four is an easier process as they don't require a lot for this to occur. This is the result of two processes. First, a cell can double its DNA but fail to divide into two, or two cells can fuse together. | Surprisingly enough, possessing eight sets of chromosomes instead of four is an easier process as they don't require a lot for this to occur.
