Genes in DNA or responsible for the traits an organism has. This is caused by Dominant and Recessive Traits. Remember that Genotypes are the genetic letters such as RR, Rr, and rr. Phenotype is physical traits.
Dominant Traits are more likely or always show in the offspring. The Dominant Genotype uses Capital letters such as RR.
Recessive Traits are less likely to show up. Their Genotype use lower case such as rr. Now genotypes of Rr have one dominant trait and one recessive trait. If the dominant trait was black fur and the recessive white fur, the offspring will be black fur because dominant traits overpower the other.
To understand how to know if an organism will have Dominant or Recessive Genes, you have to use something called a Punnet Square. Lets imagine 2 parents both have the genotype Rr. R is Black fur and r is white fur. As you can see from the chart, 3 of 4 boxes have Rr and 1 rr. Since there is a Dominant Trait with a Recessive, they will show a Dominant Phenotype, or Black fur. This has 3/4 chance and a 1/4 chance for white fur in the offspring.

Answer:
a vestigial structure
Explanation:
Vestigial structures are a rudimentary (or even functionless) version of a body part, but they have important functions in a closely correlated or evolutionarily close species, an example of which is the presence of eyes in fish of the genus Astyanax. The existence of these vestigial structures is strong evidence that evolution occurs in organisms, since this structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.
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.

Answer:
The chemical bond energy of glucose is released as ATP and heat. This is the primary source of ATP for all aerobic organisms.
