If the parents are bb and bb what percentage of the offspring will be gray? a.) 0% b.) 25% c.) 50% d.) 75%

The correct answer would be a.) 0%

The gametes produced by Bb would be B and b.

Only one type of gamete would be produced by BB that is, B.

Thus the cross would result in the production of offspring with two types of genotypes BB and Bb.

Thus, all the offspring would express dominant trait.

So, if grey is the dominant trait then all the offspring would be grey that is, 100% and if grey is recessive then none of the offspring would be grey that is, 0%.

In general, grey is a recessive trait and thus, none of the offspring would be grey.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
