    Why is this process used in wheat? Is it to make the cells and organism bigger? What are the advantages? Why is producing a sterile offspring good in this process?

    Please I do need help in understanding this.:confused:

    I'm doing the OCR spec. The part on artifical selection of wheat.

    Thanks

    Polyploidy will increase the variance between the organisms by potentially more combination of genotypes available and so may have had selectional advantage (provided it wasn't artificially selected) or it may have risen accidentally by artificial selection.
    Polyploidy doesn't necessarily produce infertile offsprings but I guess that's not helpful for your A level...
