IBD or Identical by Descent in the context of heredity and genetics implies that DNA sequences in two indoviduals may be similar due to a common ancestor from who these individuals have inherited their current geentic makeup The length of an IBD segment provides information about how far that common ancestor is from these two individuals IBS or Identity by State on the other hand refers to the similarity in DNA sequence between two individuals which may or may not be as a result of a common ancestor Similarities between two DNA sequences may arise due to singlenucleotide polymorphisms SNP in either of the two sequences That is originally thes See Answer
