Asexual reproduction means that the cell has "cloned" itself, and will therefore have the same number of chromosomes as its daughter, thus option B is correct.
        
                    
             
        
        
        
I believe the correct response is A. The population of secondary consumers would decrease, as now these organisms can't obtain energy through the food they consume which is the primary consumers as there is none and thus the population in higher tropic level dependent on them would decrease. This is the secondary consumer.
        
                    
             
        
        
        
The debate<span> you refer to is about the ethics of embryonic </span>stem cell research<span>. And, of course, since ethics is involved many would tend to oppose further research on this area because to them it violates  and does not respect life. Hope this helps. Have a nice day.</span>
        
                    
             
        
        
        
A)
Therefore:Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote).
b)
Therefore:Crossing results in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).
c)
Therefore:Crossing results in 100% (homozygous recessive).
