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.

When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale<span />
