In an experiment, the right forepaw of a developing mouse embryo is examined. The tissue and cellular structure are microscopically analyzed with histology at several developmental time points. The student finds that in the earliest time point, a population of cells located between the future digits of the paw undergoes growth-arrest and then subsequent cell death.

If a similar experiment examining limb development were conducted in a normally developing zebrafish, what observation regarding the cellular population undergoing cell death would be MOST likely?

A

The population would expand to include the entire right limb.

B

The population would condense and break off to form an additional embryo.

C

The population would proliferate indefinitely.

D

The population would no longer be observed.
