QuestionAnatomy and Physiology
Q^5. Humans carry a variety of non-functional genetic sequences, called processed pseudogenes, in their DNA. We can estimate how long ago these sequences first appeared in the genomes of our ancestors. In humans, processed pseudogenes include the three options below. Which of these would be least widespread among other primate species?
alpha-enolase psi ( 11 million years old)
AS psi ( 16 million years old)
CALM II psi ( 36 million years old)

Step 1I'll solve this step-by-step:
Step 2: Understand the Context
- Processed pseudogenes are non-functional genetic sequences in DNA - The age of a pseudogene indicates when it first appeared in ancestral genomes - The question asks which pseudogene would be least widespread among primates
Final Answer
alpha-enolase psi would be the least widespread among other primate species due to its relatively recent origin of 11 million years ago.
