Explanation:
True. diphallia is a rare condition where a male has two functioning phallic organs, and it can help (if you know what i mean) sorry this was only example i could think of
Black fur in mice (B) is dominant to brown fur (b). Short tails (T) are dominant to long tails (t). (C) 1 / 2 of the progeny of crosses Bb Tt × BB tt will be expected to have black fur and long tails.
Crosses among individuals differing in two traits is known as a dihybrid cross.
Mice with genotype Bb Tt will form 4 types of gametes, namely, BT, Bt, bT and bt, while those containing the genotype BB tt will produce gametes with 'Bt' combination.
On crossing Bb Tt × BB tt, we will get 16 possible genotypes. However, only 8 offspring will have black fur (B) and long tails (t) with the possible genotypes- BBtt and Bbtt.
Thus, on dividing 8 by 16 we get 1/2.
