Introduction to Cytogenetics and It's History Flashcards
study of heredity and variation
genetics
it is the difference in genetic sequence
variation
what is the study that refers to the transmission of traits and biological aspects from one generation to another?
heredity
three (3) primary sources of genetic variation
(1) mutations
(2) sex
(3) gene flow
areas of genetics
(1) classical genetics
(2) molecular genetics
(3) evolutionary genetics
classical genetics is based on:
mendel’s law of:
(1) law of dominance
(2) law of segregation
mendel’s law
(1) law of dominance
(2) law of segregation
(3) law of independent assortment
molecular genetics is based on:
central dogma of molecular genetics
evolutionary genetics is based on:
natural selection by charles darwin

molecular genetics
mid 1800s discoveries
the theory of evolution by natural selection
the origin of species
mid 1800s discoveries
published the origin of species, where theory requires heredity to work
charles darwin (1859)
mid 1800s discoveries
published experiments in plant hybridzations, which lays out the basic theory of genetics
gregor mendel (1866)
mid 1800s discoveries
isolated nucleic acid from pus cells
friedrich miescher (1869)
mid 1800s discoveries
proved that the genetic material is needed located in the nucleus
ernst haeckel (1871)
major events in the 20th century
rediscovery of mendel’s work
carl correns, hugo de vries, and erich von tschermak (1900)
major events in the 20th century
discovered that alkaptonuria is a genetic human disease
archibald garrod (1902)
major events in the 20th century
coined “gene”
wilhelm johannsen (1902)
major events in the 20th century
- discovered linkage between genes
- coined “genetics”
william bateson (1904)
major events in the 20th century
- discovered the science of genetic linkage
- coined “epistasis”
reginald punnett & william bateson (1910)
more 20th century events
- proved that genes are located in chromosomes through fruit flies (drosophilia)
- first discovered chromosomal differences between a male and a female
thomas hunt morgan (1910)
more 20th century events
- began the study of quantitative genetics by partioning phenotypic variance into a genetic and an environmental component
ra fisher (1918)
more 20th century events
showed x-ray mutations through fruit flies
hermann j. muller (1926)
more 20th century events
- showed that dna can transform bacteria, demonstrating dna is the hereditary material
oswald avery, colin macleod, and maclyn mccarty (1944)
more 20th century events
determine the structure of dna molecule, which leads directly to knowledge of how it replicates
james watson and francis crick (1953)
more 20th century events
solves the genetic code, showing the 3 dna base codes for one amino acid
marshall nirenberg (1966)
more 20th century events
dna base codes for one amino acid
a - adenine
c - cytosine
g - guanine
u - uracil
more 20th century events
- an enzyme found in retroviruses used in cloning genes
- makes dna and rna template
reverse transcriptase (1970)
more 20th century events
first to create a recombinant dna molecule
paul berg (1972)
more 20th century events
combined the dna from two different species in vitro then transforming it into bacterial cell (first cloning)
