Additional information Flashcards
Define auto/allozygous
autozygous - alleles originate from a common ancestor via inbreeding
allozygous - alleles are from random mating
Which of the following is NOT a way to estimate mutation rate?
Mutation accumulation experiments
Cross fostering experiments
Phenotypic screening of offspring
Genetic screening of offspring
Indirect comparison across species - math
Cross fostering experiments - plasticity
The number of neutral mutations that arise in a population that will someday be fixed is equal to
mutation rate
Name four methods to estimate mutation rates
Mutation accumulation experiments
Phenotypic screening of offspring
Genetic analysis
Indirect comparison via math
What does fixation index measure?
VARIATION of allele freq among diff populations
if Fst = 0 then both populations have equal distributions of both genotypes
if Fst = 1 then one population is all A and the other is all B
What is H2 and h2 represent in broad and narrow heritability?
H2 is Vg/Vp (genetic variance / total phenotypic variance) remember that Vg is Va +Vd (Va = additive, Vd = dominance (unreliable transmission)
h2 is Va/Vp (additive variance transmitted reliably / total phenotypic variance)
explain how physiological constraints and negative genetic correlations are not mutually exclusive (life history trade offs)
If A1 increases energy towards early reproduction then:
Physiological constraint - less energy for survival
Negative correlation - of reproduction and survival
LD coefficient D means
If greater than 0, A1B1 and A2B2 are more common than chance
its the frequency of GAMETE types possible - in mendelian itll be 0
Which is correct regarding the ideas of nominalism and realism for species?
Species are in fact real units in nature - independently evolving lineage
but high (genera/family) and lower (subspecies) are nominal and we determine them
An example of non linear selection is…
stabilizing selection
