If you selected a grey seeded plant in the f2 generation how would you determine if the plant is homozygous or heterozygous?

Depending on the F1 generation (parent) phenotype we can determine whether or not it is homozygous or heterozygous. Also, check to if the F2 grey seeded plant is a mixture of Black and white or if grey is a dominant color. If it is a mixture, it would make it heterozygous. If not and Grey is domminant it would make it homozygous.  

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
