Which of the following statements is likely TRUE of this liger cub?A) Because of the similarities between the genomes of the lion and tiger, the liger cub will likely be very fertile and bear several offspring.B) The liger cub was born because of sequence similarities between the genomes of its parents.C) Due to genetic incompatibility between the lion and tiger, the liger cub will likely be sterile.D) The cub is the result of an incompatible lock-and-key mechanism between its parents.E) The liger cub was born because of sequence similarities in the genomes of the lion and tiger; however, due to genetic incompatibility the liger cub will likely be sterile.
There are 6 base pair changes between species A and species B. Since we know the rate of change is 1 base pair every 4 million years, we know 6x 4 million is likely how long ago the species diverged. 6x 4 million = 24 million years
