Does each amino acid has its own distinctive chemical side chain attached to the center carbon of the backbone.

Bezzdna [24]

True

Amino acids are the basic building blocks of the body. They are also sources of energy, like fats and carbohydrates. However, amino acids are structurally characterised by the fact that they contain nitrogen (N), whereas fats and carbohydrates do not.

The importance of amino acids as the precursors of enzymes and neurotransmitters is often underestimated. As such, amino acids regulate almost all of the metabolic processes in the human body, and they are essential for a healthy body.

If 2 parents-both heterozygous for particular traits in a dihybrid cross are mated, how many different phenotypes will result in

andrezito [222]

If the parents are both heterozygous for particular traits their genotype would be: AaBb x AaBb ( this cross would be the F1 generation while the P generation is the one that originated the parents).
This cross would result in the folowing genotypes:
AABB
AaBB
Aabb
aaBB
aaBb
aabb
Dominant for A and B: 9/16
Dominant for A but recessive for B: 3/16
Recessive for A but dominant for B: 3/16
Recessive for A and B: 1/16
ratio: 9:3:3:1
To answer you the possible phenotypes is difficult because your question is missing information about what each gene does, but I know it would be 4 different phenotypes.
