Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Phylogenetics aims to reconstruct the evolutionary relationships and branching patterns among species based on genetic data.

Multiple choice

Which genetic marker is commonly used to study genetic diversity and population structure?

  1. Single Nucleotide Polymorphisms (SNPs)

  2. Microsatellites

  3. Mitochondrial DNA (mtDNA)

  4. Y-chromosome
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Single Nucleotide Polymorphisms (SNPs) are widely used to study genetic diversity and population structure due to their abundance, high information content, and cost-effective genotyping methods.

Multiple choice

  1. Population Genetics

  2. Molecular Evolution

  3. Phylogenetics

  4. Comparative Genomics
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Population genetics focuses on the genetic variation, allele frequencies, and evolutionary forces shaping the genetic makeup of populations.

Multiple choice

Which genetic marker is commonly used to study genetic diversity and population structure in non-human primates?

  1. Mitochondrial DNA (mtDNA)

  2. Y-chromosome

  3. Autosomal DNA

  4. Alu Insertions
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Alu insertions are repetitive DNA sequences commonly used to study genetic diversity and population structure in non-human primates due to their high mutation rate and presence in multiple copies throughout the genome.
