The Principle of Dominance
Gregor Mendel: Genes, Dominance, and Segregation
Recall that Mendel used pea
plants to study traits.
Traits are characteristics that
vary from one individual to
Traits are determined by genes.
To make a karyotype, chromosomes are
photographed while the cell is undergoing
mitosis, when they are easiest to see. Grouping
of chromosomes in a picture that combin

at position 23.
Genetics Review Guide
1. Describe the difference between phenotype and genotype.
2. Explain how using capital, lowercase, and cursive letters relates to genetics.
3. In your own words, describe the principle of dominance.
4. Who was G
Trait: Falconi anemia
Forms of the trait:
The dominant form is normal bone marrow function - in other words, no anemia.
The recessive form is Falconi anemia. Individuals affected show slow growth,
possible bone marrow failure and a high r
Punnett Squares-Crosses that involve one trait.
In weasels, black fur (B) is dominant over brown fur (b). Using the Punnett square below;
predict the genotypes and phenotypes of the offspring where the parents are both
heterozygous for the trait.
Genetics Review Guide
1. Draw a karyotype for a fruit fly. Recall that fruit flies have 8 chromosomes in
a diploid cell.
2. How does a karyotype of an individual with Trisomy 13 differ from one with
a normal number of chromosomes?

External Signals are Converted to Responses within the Cell
Evolution signals of cell signaling and local and long distance signaling
The two sexes of Saccharomyces cerevisiae secrete a signaling molecule called a factor,
which bind to
1) Carbohydrates, Lipids, Proteins and Nucleic Acids.
2) Nine water molecules
3) Amino acid in the beans are broken down via hydrolysis and distributed to the cells,
which use dehydration reaction to assemble amino acids to form new proteins.
1) Miller concluded that organic molecules may have been synthesized abiotically on the
2) Sparks which acted as lightening in the experiment provided the energy that caused
inorganic molecules to react with each other.

Concept Check :
1) Electronegativity is an atom's ability to attract electron. Oxygen has a higher
electronegativity compared to hydrogen, that is why water molecules are polar: oxygen
containing partial positive charge and hydrogen conta
