Concept explainers
a.
To determine: Whether the genes linked or not.
Introduction: Recombination frequency is a measure of genetic linkage and is used in the creation of a genetic linkage map. Recombination frequency (θ) is the frequency with which a single chromosomal crossover will take place between two genes during meiosis.
b.
To determine: A map (if linked) or two maps (if not linked), showing map distances based on straightforward recombinant frequency.
Introduction: A centimorgan (cM) is a unit that describes a recombination frequency of 1%. In this way, we can measure the genetic distance between two loci, based upon their recombination frequency.
c.
To determine: A correct the map distances for multiple crossovers.
Introduction: The crossover operator is analogous to reproduction and biological crossover. In this, more than one parent is selected, and one or more off-springs are produced using the genetic material of the parents.
