    About the Lecture

    The lecture Recombination of Chromosomes – Gene Mapping by Georgina Cornwall, PhD is from the course Understanding Genetics.


    Included Quiz Questions

    1. When the alleles are on different chromosomes.
    2. When the alleles are next to each other on the same chromosome.
    3. When the alleles are on the same chromosome, too close together for crossing over to occur.
    4. When the genes are associated with the same trait.
    1. Prophase
    2. Metaphase
    3. Anaphase
    4. Telophase
    1. The backcross between the pure dominant parent and recombinant gametes ends up with same recombinant phenotypes.
    2. Crossing over and synapsis lead to genetic recombinations.
    3. The physical exchange of genetic material due to crossing over during gamete formation leads to phenotypic recombinations in the next generation.
    4. Each chromosome acts as a linkage group which is comprised of all the genes present on it.
    5. If there is no crossing over or synapsis during gamete formation in a heterozygous individual, it leads to the formation of parental gametes.
