Chapter 19: Viruses
A Borrowed Life:
Virus: Infectious particle consisting of a little more than genes packaged in a protein coat
Cannot reproduce or carry out metabolism outside of a host cell therefore, cannot be
a living form

Lecture 13: Chromosomes
Morgan showed that Mendelian inheritance has a physical basis in the behavior of
Sex-linked genes exhibit unique patterns of inheritance
Linked genes tend to be inherited together because they ar
Offspring acquire genes from parents by inheriting chromosomes
Fertilization and meiosis alternate in sexual cycles: karyotype demonstrates homologous
Meiosis reduces the number of chromosome sets from diploi
Lecture 18: Human Genetics
Many human traits follow Mendelian patterns of inheritance
Alterations of chromosome number or structure cause some genetic disorders
Some inheritance patterns are exceptions to standard Mendelian inherit
