Speciation
A species of ant becoming two distinct species of ant is speciation.
True
Individuals with traits better suited to their environment tend to survive and reproduce more successfully
natural selection
Hardy Weinberg provides which hypothesis. Null, simple, or complex
Null
Artificial selection is performed primarily by who
humans
True or false PCR (polymerase chain reaction) is used in forensics
true
When a species becomes isolated selective pressures leading to the development of distinct physical trait indicates isolation. True or false...
True
Natural selection acts on both genotype and phenotype in an organism. Which of these are more easily observed.
phenotype
The Hardy-Weinberg equation is a mathematical equation that can be used to calculate what
the genetic variation of a population at equilibrium
Artificial selection is the same as selective breeding. true or false…
true
Mutations are changes in DNA and RNA what
sequences
A mountain range dividing goat populations into two different species is what kind of speciation
allopatric speciation
Is a giraffe's long neck for reaching high branches to eat leaves an example of evolution or adaptation.
adaptation
No mutations, no gene flow, no migration, no natural selection, and has a large population are factors of
Hardy weinberg equilibrium
Two scientists breed two different species of wolf to get a desired trait. Is this an example of artificial selection or natural selection
artificial selection
Genetic drift is a random fluctuation of what
allele frequency
A river is an example of what type of isolation
geographical
Consider a population of rabbits with varying fur colors. In an environment with snowy winters, would light or dark fur rabbits survive better.
light
Hardy Weinberg equilibrium refers to a state where allele and genotype frequency are
constant
Artificial selection is a key driver of
Domestication
A Population of birds from a mountainous area migrate to a coastal area with many species of buffalo. If the population of bird that migrated to the area and breeded with the costal bird. Will the coastal birds gene pool be altered or will the buffalos be altered.
The costal birds
Polyploidy can create what
a new species in a single generation
Natural selection is a key mechanism of
evolution
what is the allele frequency equation in Hardy-Weinberg
p + q = 1
inbreeding, line breeding and outcrossing (mating unrelated individuals). These are methods of
artificial selection
Does population genetics focus on understanding the distribution and changes in genotype or phenotype frequencies or both
Both
