Unit 3: Genetics The Cell Cycle + DNA structure/function Mitosis and Meiosis Mendelian Genetics (aka - fun with Punnett squares) DNA replication.
Exam II Lectures and Text Pages I. Cell Cycles – Mitosis (218 – 228) – Meiosis (238 – 249) II. Mendelian Genetics III. Chromosomal Genetics IV. Molecular.
Chapter 1 The Beginnings of Molecular Biology. The double helical, base-paired structure of DNA is a scientist’s dream―simple, elegant, and universal.
Inheritance of Single-Gene Differences – discovered by Gregor Mendel!!! I. I.Mendel: father of genetics A. A. Quick review of terminology B. B. Mendel’s.
THE CHROMOSOMAL BASIS OF INHERITANCE 1. A. Background 1. Genetics 1860’s—Mendel proposed that discrete inherited factors segregate and assort independently.
Overview: Locating Genes Along Chromosomes Mendel’s “hereditary factors” were genes Today we can show that genes are located on chromosomes The location.
Biology 112 Chromosomal Basis of Inheritance. Locating Genes Along Chromosomes Mendel’s “hereditary factors” were genes, though this wasn’t known during.
Meiosis Genetic Variation. Homologous Chromosomes homologous chromosomes- a pair of chromosomes that code for the same trait (one from mom one form dad)
Patterns of Inheritance Chapter 14, 15 Mendelian Genetics and its Extensions.

Objective 7: TSWBAT explain how a lethal recessive allele can be retained in the population and why lethal dominant genes are much more rare.
Nucleic Acids (DNA & RNA) Composed of C O H N & P to form the nucleotides. Nucleotides include: - a 5 carbon sugar - a phosphate group - a nitrogen base.
