    About the Lecture

    The lecture How to Create a Genetic Map – Gene Mapping by Georgina Cornwall, PhD is from the course Understanding Genetics.


    Included Quiz Questions

    1. Crossing an unknown with a homozygous recessive to determine the unknown genotype.
    2. Crossing an unknown with a homozygous dominant to determine the unknown genotype.
    3. Crossing an unknown with a homozygous recessive to determine the unknown phenotype.
    4. Crossing an unknown with a heterozygous to determine the unknown genotype.
    5. Crossing an unknown with a homozygous dominant to determine the unknown phenotype.
    1. The double crossovers are always in the lower frequency than single crossovers.
    2. Percent recombinant frequency = (Total number of recombinants/total progeny) x 100
    3. One percent recombination frequency = 1 centimorgan = 1 map unit
    4. The crossing over probability between two genes decreases with the distance separating them.
    5. The recombination frequency is used to measure the distance of a gene from the centromere of a chromosome.
