Ordered that the judgment is affirmed insofar as appealed from, with one bill of costs to the appellants appearing separately and filing separate briefs.

The plaintiff brought this action as the representative of the estate of his wife Patricia Bert, who died following a Cesarian section delivery of the Berts' fifth child. On appeal, the obstetricians, the defendants Albert Meyer, M.D., Robert L. Bialkin, M.D., P.C., Albert Meyer, M.D., and Robert L. Bialkin, M.D., challenge the finding of liability as to them, arguing that the defendants C. Ambroze, M.D., and Rockville Anesthesia Group, the anesthesiologists, were solely responsible. Both the obstetricians and the anesthesiologists claim that the damage award to the plaintiff is excessive.

The evidence was sufficient, as a matter of law, to support the jury's finding that the obstetricians were negligent in failing to recognize and treat the decedent's hemorrhage properly. It cannot be said that no valid line of reasoning existed to lead rational persons to the jury's conclusion on the basis of the evidence presented at trial ( see, Palmieri v. Long Is. Jewish Med. Ctr., 221 A.D.2d 511, 512). The plaintiff was not required to prove the precise nature of the negligence in order to establish a prima facie case ( see, Markel v. Spencer, 5 A.D.2d 400, affd 5 N.Y.2d 958; Pollicina v. Misericordia Hosp. Med. Ctr., 158 A.D.2d 194, 200). It was enough to show the facts and conditions from which the negligence of the defendants and causation may be inferred ( see, Schneider v. Kings Highway Hosp. Ctr., 67 N.Y.2d 743, 744).

The obstetricians' claim that the verdict was against the weight of the evidence is without merit. Questions concerning negligence and apportionment of fault are generally matters for the fact finder, since resolution of issues regarding the credibility of both expert and lay witnesses and the accuracy of their testimony are peculiarly within the province of the jury ( see, Seaman v. Town of Babylon, 231 A.D.2d 704).

The award of damages to the plaintiff did not deviate materially from what would be reasonable compensation under the circumstances ( see, CPLR 5501 [c]; Garcia v. New York City Health Hosps. Corp., 230 A.D.2d 766; Plotkin v. New York City Health Hosps. Corp., 221 A.D.2d 425).
