    Interdependent Assortment

    Explanation:

    As per Darwin's independent assortment theory, an offspring receives allele for any gene in equal amount from each of its mating parents. This happens because the allele pair in the parents assort independently thereby producing gametes.

    In this case, offspring's genotype is Tt. It receives T from one parent and t from other parent.

    This could be possible because TT genotype of first parent assorted to produce T and T gametes

    Like wise the second parent with genotype tt assorted independently to produce t and t gametes.
