Dr. Marilyn Menotti was trying to identify the cat whose hairs were evidence in a murder investigation. When she tested a particular genetic marker, the suspect's cat, Snowball, showed 28 and 25 copies of a TG repeat. How would you explain it if Snowball only showed 28 copies?
What will be an ideal response?
Snowball showed 28 and 25 copies of the TG repeat because one copy of chromosome B3 contained 28 copies and the other copy contained 25. If both copies of chromosome B3 contained 28 copies, this is the only result that would be seen.
