    Question: Among the given plants, which one will be the best source of aneuploids?

    Options:

    (A) Tetrasomics
    (B) Translocation heterozygotes
    (C) Autotriploids
    (D) Autotetraploids

    ✅Explanation:Autotriploids are the best source of aneuploids because they have an extra set of chromosomes. This means that they have more chances of producing aneuploid gametes, which are gametes that have an abnormal number of chromosomes. Aneuploid gametes can then combine with other aneuploid gametes to produce aneuploid offspring.📌Other Options and Explanations:
    -(A) Tetrasomics: Tetrasomics have four sets of chromosomes. While they can produce aneuploid gametes, they are not as likely to do so as autotriploids.
    -(B) Translocation heterozygotes: Translocation heterozygotes have two chromosomes that have been translocated, or exchanged, with each other. While they can produce aneuploid gametes, they are not as likely to do so as autotriploids.
    -(D) Autotetraploids: Autotetraploids have four sets of chromosomes. While they can produce aneuploid gametes, they are not as likely to do so as autotriploids.
