Why Do Investigators Use the Y Chromosome for Genetic Analysis

Why do investigators use the Y chromosome for genetic analysis?

A) The Y chromosome is technically easier to extract from cells than the X chromosome.
B) The Y chromosome rarely undergoes genetic recombination because there is no homologous partner.
C) The X chromosome passes through generations largely unchanged and is therefore useless for tracking mutations.
D) The Y chromosome mutates easily allowing ancestry to be traced over many generations.
E) When the X chromosome recombines with the Y chromosome the Y chromosome more accurately reflects inheritance from both parents.
