Recessive traits would never reappear if zygotes were given opposite alleles. 
<h3>What do you mean by Zygote?</h3>
Zygote may be defined as the outcome of the fusion of male and female gametes after successful fertilization. 
Recessive traits are only expressed when both the copies of recessive genes are inherited from the parents. 
Therefore, recessive traits would never reappear if zygotes were given opposite alleles.

Answer in the gene for that characteristic cause these different forms. ... These two copies of the gene contained in your chromosomes influence the way your cells work. The two alleles in a gene pair are inherited, one from each parent. Alleles interact with each other in different ways
 
        
                    
             
        
        
        
Temperature inversion or thermal inversion is a phenomenon during which the temperature increase when there is an increase in the altitude. It is an uncommon process that happens in the troposphere-the layer of atmosphere closest to the earth.  
When there is an increase in temperature with altitude that warm air acts as a blockage for the cool air near the surface of the earth. So this is just opposite to the normal behavior of the air, where it becomes cooler with an increase in altitude.
So how air circulation behaves during inversion?
So as we said that the cool air nearer to the earth will be blocked by a layer of warm air. This blockage will hinder the circulation of air upwards from the lower layers. Let’s see how:
•	As we know that, warm air is less dense and more buyout than cool air and normally less dense warm air is close to the earth and cool air is in above layers. But when the process is reversed, this warm air acts like a blanket for the proper circulation of air. Due to this, many environmental pollutants which normally leave the earth during air circulation get trapped in our air.  
•	The trapped environmental pollutants like nitrogen oxides and hydrocarbons get convert into harmful ozone that ultimately deteriorates the quality of air and causes problems like smog.
•	The improper air circulation also causes suspension of the harmful gases near the earth instead of allowing them to leave the earth atmosphere. This ultimately causes air pollution.  
•	When smoke will not rise, carbon dioxide will be build up in the atmosphere; this will cause greenhouse effect and global warming.
Therefore, air circulation behaves very different during temperature inversion process and poses hazardous effects on global climate.
Hope it helps! :)
 
        
             
        
        
        
Answer: 1) Organism X is positively affected by the relationship and organism Y is negatively affected
Explanation: the predator eats the prey, so the predator benefits but the prey is killed. parasites are heterotrophic organisms that live on or in another living thing and do harm to it while they themselves benefit. <3
