BIOL 479 Population Genetics and Evolution Test #1
Questions | 2026/2027 | Answers Correct | With Complete
Solutions
Can we consider the HW principle when talking about
deleterious recessive alleles? Correct Answers No. Since
selection acts on these alleles, it violates one of the assumptions
of the HW principle and we cannot use it.
Do mutation and genetic drift cause HW disequilibrium?
Correct Answers no they do not. They do change allele
frequencies but dont cause HW disequilibrium
Does assortative mating affect genotype frequencies or allele
frequencies? Correct Answers genotype frequencies, it does not
alter allele frequencies on its own.
How does inbreeding affect gametic disequilibrium? Correct
Answers since inbreeding decreases heterozygosity it will slow
the rate at which gametic disequilibrium breaks down because it
reduces the number of double heterozygotes.
is inbreeding an evolutionary mechanism? Correct Answers no
as it only changes genotype frequencies and not allele
frequencies on its own.
Is non-random mating an evolutionary mechanism? Correct
Answers no its not. Because it cant change allele frequencies on
its own.
, What 8 factors can cause gametic disequilibrium? Correct
Answers Linked loci on the same chromosome, Asexual
reproduction, Cryptic species, Genetic Drift, Founder effects,
Population bottlenecks, Migration, selection
What are allozymes? Correct Answers Biparental molecular
marker. Enzymes with different mobility in an electric field. Can
be measured using gel electrophoresis. 1 band means
homozygous, 2 means heterozygous. Co-dominant (one allele
doesn't mask the other).
What are coupling phase gametes? Correct Answers AB or ab
What are microsatellites? Correct Answers Biparental molcular
marker. Repetitive short DNA sequences. Assayed using PCR
and fluorescent analysis. non-coding and rapidly evolving.
Dinucleotide means the repeat is 2 nucleotides long, Tri means
3, etc.
What are monomorphic and polymorphic loci? Correct Answers
Monomorphic: a locus which all individuals in a population
posses the same allele (no genetic variation).
Polymorphic: a locus at which two or more alleles are present in
a population (genetic variation).
What are repulsion phase gametes? Correct Answers Ab or aB
What are single nucleotide polymorphisms? Correct Answers
Biparental molecular markers. Change in a single nucleotide.
Here we consider a single nucleotide to be a loci.
