Lecture 11 – Inheritance of Variation – Outcomes
Way in which inheritance of polygenic traits show that inheritance is not "blended"
Sex chromosomes = X chromosomes, they carry DNA polymerase, can you see green white and
People thought that inheritance is blending because most of the time it look that way
o Like they thought if a good cow milk producer mated with a cow that wasn’t a good milk
producer than their offspring would have “kind of good milk producing abilities”. Similar
with crossing a white flower with a red one, “blending” would look pink. That’s what
they thought but it is obviously wrong and Mendel proved that.
Mendel’s revolutionary idea is that inheritance is particulate
o It’s not “blending”
Characterisitics of Mendel's work that set him apart as a genetic researcher
- Polygenic traits shown continuous variation in a population
He was able to figure this out, figure out the particulateness by doing close
