How to Create a Genetic Map – Gene Mapping
Über den Vortrag
Der Vortrag „How to Create a Genetic Map – Gene Mapping“ von Georgina Cornwall, PhD ist Bestandteil des Kurses „Understanding Genetics“.
Quiz zum Vortrag
In a two-point cross to map genes A and B, you obtained 98 recombinant types and 902 parental types among the offspring. How far apart are these genes?
- 9.8 cM
- 0.98 cM
- 90.2 cM
- 9.02 cM
- 98 cM
How is a recombinant phenotype determined when using a test cross?
- The recombinant phenotype is the least frequent phenotype.
- The recombinant phenotype is the most frequent phenotype.
- The recombinant phenotype is equal to all other phenotypes.
- The recombinant phenotype is undeterminable on a test cross.
Which of the following statements are TRUE regarding gene mapping? Select all that apply.
- Double crossovers are always lower in frequency than single crossovers.
- Percent recombinant frequency = (total number of recombinations / total progeny) x 100
- 1% recombination frequency = 1 centimorgan = 1 map unit
- Recombination frequency is used to measure the distance of a gene from the centromere of a chromosome.
- The crossing-over probability of two genes DECREASES as the distance between them decreases.

Very clear and succinct. May have gone a bit too fast, but that's always manageable
