Chapter 8, Problem 14TYK
Summary Introduction
To explain: The three different processes that occur during a sexual life cycle that increase the genetic diversity of offspring.
Concept introduction: Sexual reproduction increases the genetic diversity thatenables organisms to survive better in the unfavorable environment. Genetic diversity mainly arises due to the shuffling of chromosomes during the meiosis process. Different combinations of chromosomes at metaphase 1 of meiosis occurring in the gametes are one process leading to the genetic diversity. Crossing over during prophase Iincreases the chance of producing a new combination of genes by exchanging chromosomes.

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth.
Did a patient relationship with the transfusing hospital exist?
