Practise MYP Biology questions on 5.11 Genome Mapping and Applications and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
Why is mitochondrial DNA (mtDNA) particularly useful for tracing human ancestry?
Beyond its maternal inheritance, what is a distinguishing structural feature of the mitochondrial genome compared to nuclear DNA?
During the assembly phase of genome sequencing, what do computers use to rebuild the complete genome from millions of fragments?
A genetic linkage map determines the distance between two genes based on which factor?
What is the primary impact of the 'Out of Africa' theory on the genetic diversity of human populations found further away from Africa?
It is inherited only from the father
It changes very rapidly every generation
It is only found in the nucleus of skin cells
It is passed from mothers to all children without recombination
It is a small circular genome
It contains no nucleotide bases
It consists of triple-stranded DNA
It is organized into large X-shaped chromosomes
The overlapping sequences found in the fragments
The color of the fluorescent markers
The physical size of the original cells
The proteins that were attached to the DNA
The thickness of the chromosome at that specific location
The exact number of nucleotide base pairs between them
The frequency with which the genes are inherited together
The total number of proteins the genes produce
Genetic diversity is highest in the Americas due to the late arrival of humans
Genetic diversity generally decreases as the distance from Africa increases
Genetic diversity increases because humans interbred with more species during migration
Genetic diversity remains constant because all human populations are the same age
