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
