Which way is RNA transcribed?
5' to 3'
Hardy Weinberg Assumptions
No mutation
No migration
No genetic drift
No natural selection
Hardy Weinberg Principle
(p+q)
2
= p
2
+ 2pq + q
2
= 1
genetic coding
5' to 3'
when 3' to 5', read right to left
Disruptive selection
causes both extremes of the phenotype to be favored instead of intermediate.
snail example
Stabilizing selection
does not change the mean of population, both extremes are eliminated
lizard example
Directional selection
one extreme was selected for the middle and the other extreme selected against
Reinforcement
type of natural selection
mutant tetraploid plants
are unable to mate with diploid plants
Hardy Weinberg
p =
q =
pq =
p = frequency of dominant alleles
q = frequency of recessive alleles
pq = frequency of heterozygous individuals
