A four-cell embryo normally develops into a blastocyst
consisting of trophectoderm (TE) cells on the outside and inner cell mass (ICM)
cells inside. The transplantation experiments were done with mouse embryos.
A. If a labeled cell is placed on the outside of a very early
embryo, it is likely to form extraembryonic tissues.
B. If a labeled cell is placed on the inside of a very early embryo, it is likely to form embryonic tissues.

The textbook states that cells of patients with adenomatous polyposis coli (APC) “contain a deletion of a small portion of chromosome #5, which was subsequently identified as the site of a tumor-suppressor gene called APC.” In which cells of these patients would you expect to find this chromosomal deletion?
