Answer:
Epistasis
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants
In Genetics, a gene pair has the ability to influence other gene pairs based on their combined activities which produces some effect on phenotype; this is called epistasis.
<span>The answer to the question is 0 percent. In order to have wrinkled seeds, the offspring must inherit two recessive alleles from the parents. From the cross of RRYY and RrYy, there is no way for the offspring to have wrinkled seeds as one of the parents doesn't have the recessive gene for it, the RRYY parent. Because of this there is 0 percent probability of having an offspring that has wrinkled seeds and yellow seed color.</span>

Carbon dioxide is heavier than oxygen gas. It therefore displaces the oxygen gas around a flame. Without oxygen, the combustion reaction will stop and the flame will be put out.
Further Explanation:
In order for a combustion reaction to happen, three components must be present: fuel, oxygen, and heat to cause ignition. When one of these three is removed, the combustion reaction will stop.
CO2 fire extinguishers use the difference in mass of the CO2 and oxygen molecules to stop the fire. Since CO2 is heavier, it will displace any oxygen molecules that are around the flame. When this happens, the supply of the oxygen will be limited or cut-off and the fire will eventually be put out because of the lack of oxygen. This ability to displace oxygen is also what makes using CO2 as fire extinguisher quite dangerous for the user since it pushes away the oxygen that is needed for respiration.
Other ways to put out fire include spraying liquids that absorb the heat to avoid spreading the fire further or spraying substances that coat the fuel (flammable materials) to avoid contact with oxygen gas which can lead to further combustion.
