Summary Introduction

To determine: The reason why it is incorrect to assume that certain individuals or populations carry most of the abnormal alleles found in humans.

Concept introduction: The inheritance patterns for the inheritance of traits are autosomal dominant or recessive, or sex-linked. The traits due to the genes on autosomes are inherited in a simple Mendelian pattern; they can be dominant or recessive. An autosomal dominant trait appears in individuals with a dominant allele; they can be either homozygous or heterozygous. An autosomal recessive trait appears in individuals that are homozygous for the recessive allele.
