Most of the downsides of recombinant DNA technology are ethical in nature. Some people feel that recombinant DNA technology goes against the laws of nature, or against their religious beliefs, due to how much control this technology gives humans over the most basic buildings blocks of life.
Other ethical concerns also exist. Some people worry that if companies can pay scientists to patent, buy and sell genetic material, then genetic material could become an expensive commodity. Such a system might lead to people having their genetic information stolen and used without permission. It may sound odd, but such cases have already happened. In 1951, a scientist used unique cells stolen from a woman named Henrietta Lacks to create an important cell line (the HeLa cell line) which is still used in medical research today. Her family did not know about her involuntary donation until after her death, and never received compensation, but others have profited from the use of HeLa cells.
Many people worry about the safety of modifying food and medicines using recombinant DNA technology. Although genetically modified foods seem safe in multiple studies, it is easy to see why such fears exist.
Hope this helps

Genotype is 1:2:1 (1 Homozygous tall, 2 heterozygous tall, 1 homozygous short)
Phenotype ratio is 3:1 
The heterozygous Tt and recessive tt could produce short pea plants if they were crossed.
Explanation:
Genotype is the alleles present for a particular gene. In the Punnett square we can see there will be three tall pea plants and one short pea plant but they can be either homozygous or heterozygous.
While phenotype is the exhibited trait by particular allele that is 3 tall pea plants and one small pea plant.
If Tt and tt are crossed 50 per cent chances of short pea plant is there.
 
 
        
             
        
        
        
Zero of the offspring will be bb.  Since each offspring receives one allele from each parent, all will receive a B from Dad and a b from Mom, making all of the offspring heterozygous (Bb) and brown-eyed.
 
        
             
        
        
        
I believe the correct answer would be the last option. After Frida stops exercising, it caused her body to be lack of oxygen that is why she breathes heavily to take in more oxygen from air. Also, with this, lactate is being transported to the liver. The lactate is a result of the anaerobic respiration.
