Question
Chapter 11.4, Problem 1C
Summary Introduction
To explain: Human ABO blood groups are examples of both dominance and codominance but flower color in four o’clock plants are examples of incomplete dominance.
Introduction: Not all types of inheritances follow Mendelian pattern of inheritance. Codominance and incomplete dominance have non-Mendelian pattern of inheritance. The appearance of both parental

In humans, hair texture is an autosomal trait that displays incomplete dominance. A curly-haired individual (HCHC) marries a straight-haired individual (HSHS), and do all their children have wavy hair? Show this mating.
A cross between a homozyous purple-flowedr and a homozygous white flowerd pea plants, results in offsprings with purple flowers. Does this demonstrate complete or incomplete dominance?
The human trait for blue eyes is recessive to the trait brown eyes (brown eyes is dominant). When a parent with blue eyes (bb) mates with a parent heterozygous for brown eyes (Bb), what is the expected genotypic ratio of their offspring?
