Pregunta 1
Pregunta

Respuesta
-
population
-
constant
-
forces
Pregunta 2
Pregunta
Which of these is not an assumption of the Hardy-Weinberg equilibrium?
Respuesta
-
Large population size
-
No natural selection
-
No mating
-
No mutations
-
No migration
Pregunta 3
Pregunta
The frequency of alleles can be calculated by:
Respuesta
-
p + q = 100
-
p + q = 1
-
p^2 + 2pq + q^2 = 1
-
p^2 + pq + q^2 = 100
Pregunta 4
Pregunta
The genotypic frequency can be calculated by:
Respuesta
-
p^2 + pq + q^2 = 1
-
pq^2 + 2pq + q^2 = 1
-
p^2 + 2pq + q^2 = 1
-
p1^2 + p + q = 1
Pregunta 5
Pregunta

Respuesta
-
0.0004
-
0.02
-
0.98
-
0.0392
Pregunta 6
Pregunta
Genetic drift is a change in allele [blank_start]frequencies[blank_end] due to random, [blank_start]non[blank_end] natural selection events.
Respuesta
-
frequencies
-
non
Pregunta 7
Pregunta
Stabilising selection [blank_start]reduces[blank_end] variation but [blank_start]doesn't[blank_end] change the mean. Directional selection [blank_start]changes[blank_end] the mean value toward an [blank_start]extreme[blank_end]. Disruptive selection [blank_start]favours[blank_end] the two extremes, and often leads to [blank_start]speciation[blank_end].
Respuesta
-
reduces
-
increases
-
doesn't
-
extreme
-
changes
-
favours
-
speciation
-
extinction
