WGU C653 HEREDITY AND GENETICS EXAM 2
COMPREHENSIVE STUDY GUIDE
◉ EBG.
Answer: Earth BioGenome Project; sequencing of thousands of
eukaryotes
◉ Transmission Genetics.
Answer: Principles of heredity, gene mapping, and analyzing one
individual + how its traits are passed down from one generation to
the next
◉ Molecular Genetics.
Answer: Chemical nature of the gene, its structure, organization, and
function
◉ Population Genetics.
Answer: Genetics composition of populations and how it changes
over time
◉ When was domestication of crops first introduced, and where?.
Answer: B/w 10k-12k years ago in the Middle East
,◉ Pangenesis.
Answer: Each part of the body carries genetic information regarding
that part, and the "gemmules" would travel to the gonads for
transmission during conception
◉ Acquired Characteristics.
Answer: The traits acquired in a person's lifetime become
incorporated into their genomic information and are passed down to
the offspring
◉ Preformationism.
Answer: A homunculus (tiny adult) exists preformed inside the
egg/sperm
◉ Blending Inheritance.
Answer: Offspring are a blend of parental traits (some traits do
blend, so this isn't ENTIRELY false, but for the most part it is
incorrect as individual genes don't blend)
◉ Cell theory (Schwann + Schleiden).
Answer: 1. The cell is the basic functional unit of an organism 2. Cells
can only form from preexisting cells 3. All life is composed of cells
, ◉ germ-plasm theory.
Answer: reproductive organs carry a complete set of genetic info
that is passed to egg/sperm
◉ Why did Mendel choose peas?.
Answer: Easy to cultivate, grow rapidly, many offspring, genetic
variety
◉ Cleistogamous.
Answer: A flower that stays closed and pollinates within the
unopened bud
◉ Reciprocal Cross.
Answer: A cross in which the phenotypes of the male and female are
reversed compared with a prior cross
◉ 7 Traits.
Answer: plant height, flower position, pod color, pod appearance,
seed texture, seed color, flower color
◉ 1st conclusion.
Answer: Each plant must have 2 copies of the gene from both
parents, or how would the F2 contain both wrinkled and smooth?
