A male rabbit with genotype GgBb x with a female rabbit with genotype ggbb. Set up the Punnett square and determine the expected offspring and their proportions.

Explanation:

1. Male rabbit genotype = GgBb;

so,gametes are; GB, Gb, gB, gb

female rabbit= ggbb

so, gametes are; gb  all.

2. Cross between these rabbits = GgBb× ggbb

Punnett square;

                        GB   Gb   gB    gb

cross with       gb

3. So, progeny are GgBb, Ggbb, ggBb, ggbb

So, all  genotypes are 25%.

because the asteroid belt is between the mars and jupiter orbits, it is around 2.2 to 3.2 astronomical units (au) from the sun – which is approximately 329,115,316 to 478,713,186 km. the average distance between objects is a massive 600,000 miles.

explanation:

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 enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
