Answer:
In the above question the ratio of phenotype is asked but the options given aren't according to phenotype hence the options need correction.
But, if you consider the ratio of genotype then option ( A= AaBb x aabb a. The A and B genes are on separate chromosomes ) would be the correct answer.
Explanation:
A total of <u>20</u> amino acids compose the majority of protein in living things and nine are <u>essential</u> to human.
- All living organisms, from bacteria to people, depend on amino acids for survival.
- The same 20 types of amino acids are present in all living things.
- Only 21 amino acids are required by the human body to create all the proteins required for growth and function.
- Your body can create thousands of different types of proteins with only the same 21 amino acids because they can be ordered in a wide variety of ways.
- The body is unable to produce essential amino acids. They must therefore originate from food.
- Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids.
