Inheritance patterns and alleles. In the petunia, multiple alleles result in flowers with several different
colors, such as the three shown here.

Genome: the DNA found within all of our chromosomes
THE MOLECULAR EXPRESSION OF GENES
Genetics is the branch of biology that deals with heredity and variation
Genetic variation is the root of the natural diversity amo
Chapter 25: Developmental Genetics
Developmental genetics is concerned with the roles genes play in orchestrating the changes that occur
25.1 OVERVIEW OF ANIMAL DEVELOPMENT

Chapter 20. DNA TECHNOLOGIES
Recombinant DNA technology is the use of in vitro molecular techniques that manipulate fragments
of DNA to produce new arrangements.
Once inside a host cell, the recombinant molecules are replicated to produce many identical c
Chapter 22 GENOMICS I: ANALYSIS OF DNA
Genome-the total genetic composition of an organism or species
Genomics - the molecular analysis of the entire genome of a species.
Genome analysis is a molecular dissection process applied to a complete set of chrom
Chapter 19. RECOMBINATION AND TRANSPOSITION AT THE MOLECULAR LEVEL
Homologous recombination is the process whereby DNA segments that are similar or identical to
each other break and rejoin to form a new combination.
During site-specific recombination, no
15: GENE REGULATION IN EUKARYOTES: TRANSCRIPTIONAL REGULATION
Gene regulation - level of gene expression can be
controlled to be expressed at high or low levels.

13.1 THE GENETIC BASIS FOR PROTEIN SYNTHESIS
1. Explain how the work of Garrod indicated that some genes encode enzymes.
2. Analyze the experiments of Beadle and Tatum, and explain how their results were
Chapter 3: Chromosome Transmission during Cell Division and Sexual Reproduction
During cell division, eukaryotic cells can sort their chromosomes in two different ways.
o One process called mitosis sorts chromosomes so that each daughter cell receives the

5.1 MATERNAL EFFECT
Maternal effect- the genotype of the mother directly determines
the phenotype of her offspring
o The genotypes of the father and offspring do not affect the
phenotype of the offspring
o Explained by
Chapter 14: Gene regulation in bacteria
Gene regulation - phenomenon in which the level of gene expression vary under different conditions
o Unregulated genes AKA constitutive genes - have constant levels of expression in all conditions
Encode proteins t
