Wednesday 1 Feb 2017 Entry Task
What 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). Agenda

Punnett Square Practice Worksheet
Chpt 11 Workbook Housekeeping
Chpt 11 exam scheduled for Friday, 10 Feb. • Kahoot review on Thursday, 9 Feb. Mendel’s Principles
Segregation 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 Principles
Genotype vs Phenotype:
• Genotype = genetic makeup
• Phenotype = physical traits (observable)
p. 314 Punnett Square
Punnett Squares:
• Simple diagrams that use mathematical probabilities to help predict the genotype & phenotype combinations in genetic crosses.
p. 315 Independent Assortment
Principle of Independent Assortment:
• Genes for different traits can segregate independently during the formation of gametes.
p. 317 Punnett Square Practice
Complete the “Punnett Square Practice Worksheet”.
• Worksheet will be checked Friday, 3 Feb., @ the beginning of class.

Thursday 2 Feb 2017 Entry Task
If 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) Agenda

Punnett Squares and a Dihybrid Cross (8:31):
• Link: https://www.youtube.com/watch?v=qIGXTJLrLf8 Other Patterns
Beyond 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 Patterns
Beyond 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 Patterns
Incomplete Dominance:
• Some alleles are neither dominant nor recessive.
• Not completely dominant.
• Heterozygous phenotype lies between homozygous phenotype.
p. 319 Other Patterns
Codominance:
• Phenotype produced by both alleles clearly expressed.
• Colors appear separately.
p. 319 Other Patterns
Multiple Alleles:
• Genes with more than two alleles.
• Two alleles is the exception not the rule.
• Ex. Humane gene for blood type.
p. 320 Other Patterns
Polygenic 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 Environment
Environmental conditions can affect gene expression & influence genetically determined traits.
