Genetic Mapping

Genetic Mapping starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Genetic Mapping.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A geneticist observes a recombination frequency of 20% between two genes. What does this indicate about their physical proximity?
A researcher observes 8 recombinant offspring out of 100 total. What is the recombination frequency?
A scientist finds that two genes have a recombination frequency of 0%. What does this suggest?
A three-point test cross is used to determine the order of three genes. What is the main advantage of this method?
Describe how molecular markers have improved genetic mapping.
Describe how recombination frequency is used to construct a genetic map.
Describe the relationship between crossing over and genetic mapping.
Describe the relationship between recombination frequency and gene distance.
Explain the difference between a genetic map and a physical map.
Explain the role of test crosses in genetic mapping.
Explain why double crossovers can lead to underestimation of genetic distances.
Explain why genetic mapping is important in agriculture.
Explain why genetic maps are important in identifying genes associated with diseases.
If the recombination frequency between gene A and gene B is 5%, and between gene B and gene C is 10%, what is the maximum possible distance between gene A and gene C?
If two genes are 50 centimorgans apart, are they likely to be on the same chromosome?
The frequency of recombination between two genes is 10%. What is the distance between them in centimorgans?
What is genetic mapping?
What is the main limitation of using recombination frequency to estimate genetic distance?
