Chapter 16 Summary 

2/20/11

Chapter 16 starts off talking about Mendel's Law of Inheritance.  We learn from Mendel that two alleles of a gene segregate during the formation of eggs and sperm so that every gamete receives only one allele.  The next section is a very brief lesson that discusses the chromosome theory of inheritance.  This theory explains how the steps of meiosis account for Mendel's laws of inheritance.  Each is located at a particular locus on a chromosome.  Section 16.3 discusses that inheritance patterns in humans are determined from a pedigree analysis.  The next section talks about x-linked inheritance patterns and sex chromosomes.  It is more likely for a male to be color blind because color blindness is determined by a recessive X chromosome and males only have one X chromosome.  In section 5, we learn about recessive inheritance, incomplete dominance, codominance, and sex-influenced inheritance.  The last section discusses the probability of a gene getting passes on to an offspring.
