Aperson with a phenotype of hbss has sickle cell disease. a person with a phenotype of hbas allele carries the sickle cell trait. a person with a phenotype of hbaa does not have sickle cell disease and does not carry the trait. the punnett square shows the phenotype of two people carrying the sickle cell trait. hb a s a aa as s as ss what are the chances that their offspring will have sickle cell anemia?

An individual with a phenotype of HbSS exhibits sickle cell disease. An individual with a phenotype of HbAS allele carries the sickle cell trait. An individual with a phenotype of HbAA does not possess sickle cell disease and does not carry the trait. The Punnett square demonstrates the resulting progeny after a cross between the two individuals of the genotype HbAS, who are carrying the sickle cell gene. The probability of getting sickle cell disease in the offspring comes out to be 25 percent.

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
