  • question_answer
    One of the parents of a cross has mutation in its mitochondria. In that cross, that parent is taken as a male. During segregation of \[{{F}_{2}}\]progenies that mutation is found in:                                               

    A) one-third of the progenies                         

    B) none of the progenies

    C)  all of the progenies                                                       

    D) fifty per-cent of die progenies

    Correct Answer: B

    Solution :

                    It is the female reproductive cell which usually carries more cytoplasm and cytoplasmic organelles than the male cell and hence, naturally would be expected to influence non-Mendelian traits. Since in the present case the male parent (not female) had mutation in mitochondria, there are neglible chances of the mutation being inherited.
