Answer:
option B: Polygenic inheritance
Explanation:
Polygenic inheritance in genetics and plant breeding can be defined as a type of inheritance whereby one or a single trait or characteristics(color) is controlled by multiple genes (two or more genes). it is a continuous variation that depicts a normal distribution curve
the phenotype of a plant or an animal increases if when there is an increase in the number of genes controlling a particular trait or characteristics. polygenic inheritance are non-Mendelian form of inheritance in nature and a single trait expressed is as a result of the interaction of many or multiple genes that are quantitative genes in nature. examples are weight, skin color, height, e.t.c

DNA is synthesized in the middle part of Interphase, which is usually denoted S in the series G1 - S - G2 </span><span>"There are 3 stages of interphase: G1 in which the cell grows and functions normally. Once it grows too large it enters the synthesis (S) phase. In S phase the cell makes exact copies of its DNA. It is now ready for G2 phase where it makes sure all of its chromosomes and organelles are ready for mitosis."</span>

<span>During nitrification, ammonia is changed back into nitrate.</span>
Nitrification is a three-step process of oxidation of ammonia. It is an aerobic process performed by small groups of autotrophic bacteria (<span>Nitrosomonas,
Nitrobacter</span>).
First step- ammonia to hydroxylamine,
Second step-hydroxylamine to nitrite,
Third step-nitrite to nitrate.
Nitrification together with ammonification is part of a nitrogen cycle.
