In a eukaryote, which of the following describes the most likely outcome when gene duplication occurs in one member of a gene pair?
A) creation of a pseudogene or a gene with a new function
B) creation of an operon that uses common regulatory elements
C) addition of an intron in the original gene
D) nondisjunction of that chromosome during the next round of cell division.

Question

Gene duplication can lead to the creation of a pseudogene or a gene with a new function. This process allows for genetic diversity and the evolution of new functions without losing the original gene's function. Operons are primarily a feature of prokaryotes, intron addition is not directly related to gene duplication, and nondisjunction is a chromosome segregation error, not a direct outcome of gene duplication.
