CB 14.6
PhenotypeGenotype
Genes code for proteins (or RNA). These gene products give rise to traits…
It is rarely this simple.
CB 15.10
Sex-linked traits: Genes on the X chromosome
No one affected, female carriers
50% of males affected, 50 % female carriers
50% affected, female carriers
A= normal ; a= colorblind
CB 26.13
Endosymbiotic Theory - proposed origin of mitochondria and chloroplasts from free-living bacteria to cellular organelles
CB 13.5
Mom provides 50.000275% and Dad provides 49.999825% of DNA to offspring.
… because Mom provides 100% of mitochondrial DNA

The mutation rate in human mtDNA is one nucleotide change per 20,000 years.ORA difference of one nucleotide between two people indicates a common relative 10,000 years ago.

•93-95% of genetic variation within population.
•3-5% of genetic variation occurs between populations.
Relationships of different people using mtDNA.
Tsar’s Family
(bonus info not covered in class and will not be on the exam)
During the Bolshevik revolution, the Tsar’s family was captured and
executed.
Tsar’s Family
There are many stories about what happened to their youngest daughter
