Described herein are polymerase variants that are exonuclease deficient. Some variants retain the strand displacement capability comparable to the wild-type or parental polymerase. Some variants have a strand displacement capability that is improved relative to the wild-type or parental polymerase. The variants may have an extension rate that is greater than the wild-type or parental polymerase. The variants may have a waiting time that is less than the wild-type or parental polymerase.
