Do Now:• Who was Darwin? Why was he

important?• A theory of biological evolution developed

by Charles Darwin and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. Also called Darwinian theory.

Europa, Europa• Hitler’s Nuremburg Race Laws

Homework – Part I• Read & take notes on the following pages 308 –

312 for Thursday. Complete the 10% Summary worksheet. Worth a quiz grade

• Genetics Alleles• Fertilization Principle of Dominance• Trait Segregation• Hybrids Gametes• Genes

Homework Part II - Project

• Find your project assignment. And look up the condition and summarize the topic in 50 to 100 words.

Do Now part II

• Write down either / or five things that are important about genetics or what you know about genetics. You must have at least five. Please complete in the next five minutes.

New Material• Is the next slide real or photo-shopped?

New Material• The last slide was real!

New Material• Occurs rarely throughout the world, but if

in an area where the population is small or families are too closely related to one another (the British Royal Family). It is know as “genetic drift.”

Gregor Mendel – Father of modern genetics

Mendel choose Pea cells due to their simple design

ExploredFertilization -Hybrids Pollination Gametes

Heredity:

The sum of the characteristics and potentialities genetically derived from one's ancestors

What is genetics?

The study of heredity This came from Darwin’s study

of evolution. For example: Breast Cancer is

passed through families. .

Traits

The specific characteristic of an organism such as height, or color

Traits

Alleles - gene types (short, tall, brown or blue eyes,...)

Law of Segregation

Each parent passes along one trait (allele) to the off-spring

Phenotype

How it looks, can be very different from what it does or is made up

GenotypeGene make up, for example

A person can be tall because both parents are tall, or one parent being tall or in some cases even if both parents are short.

Why?

GenotypeHomozygous – means both of the same.Same type of alleles (Tall – Tall

or Short-Short) Heterozygous – 2 different alleles (Tall –

Small)

Different types of Genotypes

Homozygous –

Same type of alleles

(Tall – Tall)

Heterozygous –

2 different alleles (Tall – Small)
