What is the most probable explanation for the continued presence of pseudogenes in a genome such as our own?

#SCPH06 I Botany

  1. They are genes that had a function at one time, but that have lost their function because they have been translocated to a new location.

  2. They are genes that have accumulated mutations to such a degree that they would code for different functional products if activated.

  3. They are duplicates or near duplicates of functional genes but cannot function because they would provide inappropriate dosage of protein products.

  4. They are genes that are not expressed, even though they have nearly identical sequences to expressed genes.
