Chpt 11 Introduction
Introduction to Genetics
Essential Question:
How does cellular information pass from
one generation to another?
Chpt 11 ObjectivesYou will be able to answer the following questions.
• What are the key vocabulary of genetics?
• What is a Punnett square & how does it show the possible
genotype & phenotype of offspring?
• What are other patterns of inheritance?
• What is epigenetics & its relation to environmental factors &
the nature vs. nurture argument?
Chpt 11 VocabularyComplete the vocabulary foldable within your notebook.
• Definitions should be written behind each word tab.
• Section 11 vocabulary foldable can be located @

Entry TaskWhat are the possible allele combinations for the parents of a
short homozygous recessive (tt) pea plant?
• Both parents are homozygous recessive (tt)
• Both parents are heterozygous (Tt)
• One parent is homozygous recessive (tt) & the other is
heterozygous (Tt).

Mendel’s PrinciplesSegregation used to predict outcomes.
• Allele segregation just as random
as a coin flip.
F2 generation contains different
combinations of alleles.
• Homozygous vs Heterozygous
p. 314
Mendel’s PrinciplesGenotype vs Phenotype:
• Genotype = genetic makeup
• Phenotype = physical traits
(observable)
p. 314
Punnett SquarePunnett Squares:
• Simple diagrams that use mathematical probabilities to help
predict the genotype & phenotype combinations in genetic
crosses.
p. 315
Independent AssortmentPrinciple of Independent Assortment:
• Genes for different traits can
segregate independently during
the formation of gametes.
p. 317

Entry TaskIf a heterozygous brown dog is crossed with a homozygous
white dog, what are the possible offspring genotypes &
phenotypes? (draw a punnett square to solve)
• Genotypes = Bb (2) & bb (2)
• Phenotypes = brown (2) & white (2)

VideoPunnett Squares and a Dihybrid Cross (8:31):
• Link: https://www.youtube.com/watch?v=qIGXTJLrLf8
Other PatternsBeyond Dominant & Recessive:
Exceptions to Mendel’s work.
• Genetics is more complicated.
• Majority of genes have more than two alleles.
• Some traits controlled by more than one gene.
p. 319-320
Other PatternsBeyond Dominant & Recessive:
Think, Pair, & Share
• Designate in your groups who is reading which sections.
- Incomplete Dominance (p. 319)
- Codominance (p.319)
- Multiple Alleles (p. 320)
- Polygenic Traits (p.320)
• Silent (no talking) read & make notes for 5 min.
• One person will share for 1 min., then the group will have 1
min. to ask questions. Next person will share, etc.
p. 319-320
Other PatternsIncomplete Dominance:
• Some alleles are neither dominant nor
recessive.
• Not completely dominant.
• Heterozygous phenotype lies between
homozygous phenotype.
p. 319
Other PatternsCodominance:
• Phenotype produced by both alleles clearly expressed.
• Colors appear separately.
p. 319
Other PatternsMultiple Alleles:
• Genes with more than two alleles.
• Two alleles is the exception not the rule.
• Ex. Humane gene for blood type.
p. 320
Other PatternsPolygenic Traits:
• Traits produced by the interaction of several genes.
• Polygenic = “many genes”.
• Show a wide range of
phenotypes.
• Ex. Humane skin color
controlled by 4 different
genes.
p. 320
Genes & the EnvironmentEnvironmental conditions can
affect gene expression & influence
genetically determined traits.
