Genetics Exam Questions and
answers graded A+
What are the three divisions of genetics? - ANS✅✅1. Transmission Genetics
2. Molecular Genetics
3. Population Genetics
What are four traits that make model organisms ideal for studying genetics? - ANS✅✅1. Fast
generation time
2. Easy to culture or house
3. High number of offspring
4. Adaptable to laboratory conditions
In point form, list the history of genetics. Please include the date, the major person/people involved
and the contribution to the field of genetics. - ANS✅✅833-859 BC - Assyrian and Babylonians:
Pollination of date palms
1839 - Schledien and Schwann: cell theory
1859 - Charles Darwin: evolution through natural selection
1866 - Mendel: Inheritance; pea plant experiment
late 1800's - August Weismann: germ plasm theory
1902 - Sutton: chromosome theory
1910 - Thomas Hunt Morgan: inheriteance; fruit fly experiments
1939 - Watson and Crick: 3D structure of DNA
1953 - chemical structure of DNA (DNA vs. RNA)
1966 - Kary Mullis et al. - PCR
1990-2003 - human genome project
How does the amount of DNA and the genome differ between prokaryotes and eukaryotes? -
ANS✅✅Prokaryotes tend to have less DNA than eukaryotes. The DNA in prokaryotes is located in
the nucleoid region because they lack a nucleus. DNA in eukaroytes is found within the nucleus.
Which mechanism brings about recombination between gene pairs that are located on a single pair
of chromosomes?
