Answer:
Explanation:
Mendel propel two laws The law of inheritance and that of independent assortment of gene.
Independent assortment of gene explain that alleles of a gene assort independently and that different Allele can show different phenotypic effect and differences. This means that in a gene where we have 2 allele they can both show individual difference where one can have a dominant effect over the other and the other allele is recessive.
This law does not take care of linked gene where alleles don't separate after crossing over sister chromatids but are rather inherited together given rise to complex inheritance. 
Pleiotrophy effect of a gene where a gene is having many effects.
 
        
             
        
        
        
Option no. 2 a decrease in the release of oxygen gas
It is not simple because the process of growing crops, it needs more fertilizers, and processing the plants converting it to fuels needs a lot of energy. As much energy is used during the production from natural gas. The way of making biofuels it contains cellulose. Cellulose                          
                                                                                                      
        
             
        
        
        
Yes because sucrose is sugar and it is transfered so we can eat it
