Mendelian Genetics

DNA

Guanine & Cytosine

Adenine & Thymine

Double helix

Deoxyribonucleic acid

Traits

Not Relevant

Most and least common trait in population

Most beneficial and least beneficial

Unrelated to whether the trait is good or bad

Subtopic

Dominant

is observable

Stornger

It is the only observable trait when it is present

Recessive

Is not observable

Weaker

It is only observable when it is the only allele in the individual

Gregor Mendel

Experiments

Plant Hybridization

Showed different

He crossed varieties that were different in one trait. Tall x Short

Choose 7 traits expressed in a distinctive manner such as plant height and seed colour

Conducted studies with edible pea plants (Pisum Sativum)

Education

Also studied anatomy and physiology of plants

Devoted his time while at vienna to physics and mathematics

Failed teacher exam send to University of Vienna for 2 years to benefit from a new proram of scientifc instruction

2 year philosophy program at the philosophical institute of the university of Olmutz

Life

Poor Farming Family

Father of Genetics Even though he didn't know about

Austrian monk, born as Johann but took on Gregor as a monk

Czech Republic July 20, 1822-January 6, 1884

Mendelian inheritance

Three major patterns are

Inheritance patters in a

Pedigrees

Shows the presence or absence of a

Preferred method of collecting family history info

Patterns of Inheritance

Mitochondrial

Leber's heredity optic neuropathy, kearns sayre syndrome

Subtopicappear in ever generation

affected both genders

Subtopicected males often present in each generation

Subtopics more frequently affected

X linked

Can have affected Males and Females in same generation

Females more frequently affected

Autosomal

Not typically seen in every generation

.

Offsprings have parents that are carriers

Autosomal

affect offspring has affected parent

Ever genertation

Chromosomes

Pairs

Gene Technologies

Benefits

Faster growing plants and animals

removes

Uses

Makes changes in

Original Human Genome Project took 13 years and cost 3 Billion$ now it costs 1000$ and takes three days

First were developed in late 1900s CRISPR made is easier to edit genes

Disadvantages

Can affect relationships with the knowledge of a genetic mutation

Creation of deadly genetic viruses

Disease

Mutations

Topic principal

Laws of segregation

Punnett square

Used to predict

Phenotypes

Genotypes

One gene compy which is randomly selected

Allele

Organisms will have 1 or more

A variation of information that is used in chromosomes
