What is meant by genetic homology?
A. genetic traits that appear similar despite sequence differences due to redundancies in the genetic code
B. genetic traits that are found in unrelated species due to functional requirements of how genes are encoded
C. genetic similarity between two alleles in an individual due to inbreeding among its parents
D. genetic traits that are similar due to similar environments
E. genetic sequences that are similar due to the shared heritage of two organisms

homology is the existence of shared ancestry between a pair of structures, or genes, in different species. A common example of homologous structures in evolutionary biology are the wings of bats and the arms of primates. Evolutionary theory explains the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor.
