Constructing a Pedigree
Some basic rules for making a pedigree:
1. Males are represented as squares
2. Females are represented as circles
3. A marriage is represented by a horizontal line connecting a circle and a square
A. Double membrane-bound organelle with its own DNA
and outer and inner membranes.
B. The inner membrane divides the mitochondrion into
inner and outer compartments. It is extensively folded,
1. outer compartment acidic (between inner
A. This is the second stage of anaerobic
B. Review of the products of glycolysis:
1. 2 ATP
2. 2 NADre
3. 2 pyruvic acid molecules
C. Where do these products go next?
1. back to glycolysis or provides
energy for cellular processes
Duration of the Cell Cycle
The length of the cell cycle is important because it determines
how quickly an organism can multiply. For single-celled organisms, this
rate determines how quickly the organism can reproduce new,
independent organisms. For highe
AICE Biology Chi Square Practice Problems
1. A newly identified fruit fly mutant, cyclops eye (large and single in the
middle of the head), is hypothesized to be autosomal dominant. The
experimenter started with homozygous wild type females (yes, virgins)
I. Gregor Mendel solved the mystery of heredity.
A. Classical assumption 1 constancy of species
B. Classical assumption 2 direct transmission of traits
II. Mendel & the Garden Pea
A. Why Mendel chose the pea
1. He knew he could expect to observe segregati
AP Biology Genetics Problems
Monohybrid Crosses (One-trait)
1. Sample Problem: The Gene for tall is dominant over dwarf in the garden pea plant used by
Mendel. A pea plant that comes from a line of plants that are all tall is crossed with a dwarf pea
Inbreeding is bad for plants too
Genetic diversity within a species helps fields to bloom.

MUTATIONS AND DELETERIOUS ALLELES
A. A MUTATION IS .
B. ARE MOST MUTATIONS GOOD OR BAD?
C. RELATIONSHIP BETWEEN MUTATIONS AND NATURAL SELECTION?
D. WHY ARE FEW DOMINANT DELETERIOUS ALLELES PRESENT IN
E. WHY DO RECESSIVE MUTATIONS
1. Chromosomal DNA replication is usually initiated at specific sites called
2. These sites contain specific base sequences at which special replication initiator proteins bind. It
is usually a region of mostly A-T
1. Make one nucleotide. Start with the purple piece that represents the deoxyribose
sugar with each peg representing one of the five carbons of deoxyribose.
2. Orient the carbon #1 at the top and attach a clear tube to it.
ONE GENE/ONE-POLYPEPTIDE HYPOTHESIS
1. What is the one-gene/one polypeptide hypothesis?
2. Archibald Garrod
a. What is his contribution to this hypothesis?
b. Briefly explain his research.
c. What is/are his conclusion(s)?
TRANSCRIPTION AND TRANSLATION
AT THE END OF THIS CHAPTER YOU SHOULD BE ABLE TO:
1. compare and contrast DNA and RNA with respect to size, composition, structure, and
2. describe Cricks central dogma.
