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.

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.

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)

• Kahoot review on Thursday, 9 Feb.

• Study guide handed out on Monday, 6 Feb.

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.
