What are the two dominant alleles ?



○ Crop losses are large in general

■ We use pesticides to have less loss

■ Bugs/Pests that have the genes to resist, or withstand the poisons will survive

● Evolves them into eventually making the pesticide useless

■ As time progresses pesticides no longer work

■ Next generation of Pesticide comes out and then the cycle repeats

○ Civil war

■ Lots of deaths because there was no defense against bacteria/infection ○ World War 2 We also discuss several other topics like What is luminosity?

■ Had Penicillin

● Killed bacteria and prevent infection

● Mass produced

● Alexander Fleming

○ Tuberculosis

■ Many different treatments that no longer work

● Multi­Drug­Resistant Tuberculosis is currently untreatable and will


What are the two recessive alleles?



kill the person

○ MRSA controlled disease If you want to learn more check out Why is biodiversity important?

■ Flesh­Eating Bacteria

● Now resists the treatment

● Very limited treatments

● Few strains that actually cure you

○ C. Diff

■ Causes severe problems in your guts

■ Generates Ulcers

■ Currently able to control it

■ Fecal Transplant fixes it

○ Antibiotic use has increased 36%

○ 80% of all U.S. antibiotic use is to increase the growth of farm animals ○ Long­Dreaded Superbug found in Human and Animals in China and the U.S. ■ Resistant to all of the current drugs We also discuss several other topics like What is a fake treatment given to the control group to mimic the experience of the experimental group?

■ Promiscuous bacteria

● Ability to easily swap genetic material

■ Superbug able to possible give the resistances to other bacterial diseases ● Microbiology


Define punnett square.



○ Human Body is full of bacteria

■ Good Bacteria

■ Generally regional in your body

● Lamarck's Ideas

○ Offspring acquire characteristics that their parents got during their lifetime

● Offspring Blend together the traits of their parents

● Gregor Mendel and His Peas

○ Growing peas in czechoslovakia for the monastery he lived in

○ Also kept honeybees

○ Noticed patterns of inheritance in the peas that he grew

○ Peas had discrete ("either­or") traits 

■ Flowers are either red or white

■ Tall or short

■ Inflated or Pinched

○ Breeding true

■ If parents are both red flower

● Red flower

■ If parents are both white flowers

● White flower

■ If parents are red and white

● All Red flower

○ Conclusions

■ 'Inheritance Units' Don't forget about the age old question of What is the difference between civilizations and small scale societies?

● Genes 

○ Come in pairs

○ Each has two Alleles 

■ Alleles make up the two hidden traits that affect a

gene

■ One from each parentIf you want to learn more check out What is the equation of density?

■ One allele can 'mask' the other If you want to learn more check out The chief steward reports to the f&b manager and is responsible for?

● Dominant​ alleles can 'mask' recessive​ alleles

○ For any gene you might have

■ Dominant have capital letters 

■ Recessive have lowercase letters 

● Two Dominant alleles

○ AA

● Two Recessive alleles

○ aa

● One Dominant and one Recessive allele

○ Aa

■ Two of the same

● Homozygous 

○ AA or aa

■ Two that are different

● Heterozygous 

○ Aa

■ Genotypes

● The genes that are inside of you

■ Phenotypes 

● The traits that are visible

■ Punnett Square

● The square where you place in the alleles to form the offspring

● Dominant traits always go first when written

● Sickle­cell disease

○ Sickle­cells can't pass through small blood vessels

■ Can't carry as much oxygen

■ Recessive trait, when the person is Heterozygous they are resistant to many diseases, but when homozygous recessive they die very young
