Answer:
four phenotypes appear in the ratio 9:3:3:1
Explanation:
<em>For a dihybrid cross in which the two genes concerned obey simple dominant/recessive law and are independently assorting, </em><em>four phenotypes are produced in the ratio 9:3:3:1. </em>
The dominant gene takes up the largest ratio (9/16) while the recessive gene takes up the smallest (1/16). Any deviation from 9:3:3:1 and the number of phenotypes produced from a dihybrid cross is an indication that the genes involved do not obey Mendelian laws.
Organic molecules are more complex than inorganic molecules. They generally have carbon hydrogen and carbon oxygen bonds.
<h3>
What are organic molecules?</h3>
Organic molecules generally have carbon, oxygen and hydrogen bonds. Organic chemistry is a branch of chemistry that deals with organic chemistry.
Organic molecules are compounds with complicated structures. Carbohydrates, lipids and proteins are some kind of organic molecules. Organic molecules are generally larger than inorganic molecules.
Carbon chain in organic molecules can be straight, branched or ring shaped. This compounds have some functional groups such as hydroxyl, methyl and carbonyl.
Therefore, Organic molecules are more complex than inorganic molecules. They generally have carbon hydrogen and carbon oxygen bonds.
