For this cartoon the biological concept is reproduction. Both parents thing that the child will have their dominant gene of having a human head, but in the end the child gets both undesired parts – the recessive gene is not having a head, and the child is a combination of fish and horse bodies. The [...]

The tortoises of the Galapagos Islands are the most interesting and perplexing subjects for many scientists that support the idea of evolution, including the famous Charles Darwin. Giant tortoises were very common during the Pleistocene era, but now most of them are extinct (those on the islands of Mascarenes became extinct in 1804, and those [...]

Joke: Biology is the only science in which multiplication is the same thing as division.

Explanation: Multiplication, or reproduction, occurs by the biological process of cell division.

This cartoon/image references ATP, which is also known as Adenosine triphosphate. It is a high-energy transfer molecule, and multifunctional nucleotide. It is necessary to know that energy and ATP are associated with one another in order to understand what is comical about this cartoon. Although it somewhat incorrectly uses energy and ATP interchangeably, it is [...]

The re-posting of this cartoon is not permitted, but I have posted its link. 
This cartoon was by far one of the most clever biology cartoons I came across. It details the “positions” various biological elements of the body. For instance, the anti-bodies are solely [...]

It shows how the DNA must curl together to form cromosomes before mitosis can be successful in producing a fully functional cell.

The eye has been evolving for over hundreds of millions of years. Animals needed sharp vision to be able to hunt their food efficiently. Likewise, we need our eyes to be able to see danger such as the ability to spot a snake in the grass. Thus the eye has evolved and adapted based on [...]

I have to come up with a bio joke so this is gonna be hard…
Hmm… Well here goes nothing!
One hot sunny day one mitchondria said to another, “Boy it sure is as hot as cell in here!”
GET IT CAUSE THEY ARE MITCHONDRIA IN A CELL!!! I’m sorry…

Birds of Paradise began splitting off from their bland kin millions of years ago, evolving into today’s 38 eclectic species. Of these, 34 live only on New Guinea and its satellite islands.
Bird of paradise evolution is fundamentally based on the evolution of courtship-related traits and behaviors. The variety and beauty of the plumes, shields, streamers, [...]

Neanderthal have always been thought of as having become extinct due to competition with more modern humans. But recent studies have determined that neanderthal genomes are present in many modern humans indicating that they also integrated into the rest of the human society. This confirmed the reason behind there being certain groups of [...]

 
 
One of the most debated topics in modern science, still to date is the evolution of the human brain. The most common explanation is usually related somewhat to the theory of naturalistic evolution; however, this idea claims that small and random changes occur over a very long period of time that eventually leads to an [...]

A genetic disorder that I find interesting is albinism. Albinism results from the defect in the enzyme that helps in changing the amino tyrosine into pigment. The gene for this defect is located on autosomes, which contain the genes for our characteristics and we have two copied on them (one from each parent). In people [...]

For this post, my topic of interest regarding genetics will be twins as they “run” in my family.
Basically, twins are two offspring that result from one pregnancy, regardless of species.  Due to space limitations and differences in nurturing a single birth as opposed to multiples, twin pregnancies on average are 3 weeks shorter than that [...]

Ocular Albinism is a genetic condition affecting the eyes, and occurs because of mutations in the GPR143 gene. The retina is the light sensitive tissue in the back of the eye, and when afflicted with ocular albinism, it is unable to function properly because of an increased sensitivity to light, known as photophobia. Pigmentation of [...]

One topic of genetics that personally interests me is that of cloning. Cloning is the process of making a genetically identical organism without the means of reproduction of a sexual nature. It has been used for some time now to make many types of plants through the means of growing a new plant from a [...]

I’ve always wondred why my sister and I, coming from the same parents, look so different. People say we have the same smile and the same facial expressions, but most of the comments we get say, “You don’t look like sisters.” She has naturally blonde hair, green eyes, and pale skin, while I have brown [...]

Sickle cell anemia is a genetic disease that effects 1 out of every 500 African Americans. The disease is caused by a mutation in DNA which then leads to the synthesis of a different protein. The HBB gene is the gene that is responsible for passing on the mutation. Hemoglobin, the red blood cell consists of two [...]

Escherichia coli
The bacterium known as E. Coli is a common one. Present in almost all humans it is basically everywhere. It is a relatively harmless bacteria, usually doing nothing but the occasional upset stomach when ingested but it is still relatively common. Within 40 hours of any childs’ birth it has already begun to colonize [...]

Is one born an athlete or can a person with no athletic genes be just as successful in a particular sport? Is there an advantage to having parents who were athletic? Or is sports performance solely based on hours of hard training and adapting to the demands of the sport? Many studies show that genes [...]

Cloning is an interesting field of genetics. A cloned organism has the exact genetic makeup of another individual. A relatively new phenomenon, cloning first came into the public eye in 1997 with the successful clone of Dolly the sheep. Since then, a variety of different animals have been cloned, including mice and cats. However, one [...]

Charles Darwin traveled to the Galapagos islands as a naturalist on the HMS Beagle. He took note of the characteristics of the various organisms on the islands, which were primary examples of isolated communities as the island format prevented many from intermingling.
He noticed a surprising trend among the finches. While they all appeared related in [...]

Thanks to the rapid growth of the Human Genome Project, it has been predicted that biology will be the most popularly studied science of the 21st century. By 2009, leading researchers expect that the sales of DNA-based products and technological services will reach an excess of $45 billion. At the completion of the Human [...]

DNA testing in general has become more and more popular, one of these tests can trace Y-chromosomes and their movement across regions this works well to some degree because it can only be traced back down only one chain but yet it can be matched up against near identical Y chromosomes [...]

Sickle Cell Anemia:
Sickle Cell Anemia also called Hemoglobin SS disease is a genetic disorder that causes red blood cells to be abnormally shaped. Normal red blood cells are shaped like a disc where as a person that has sickle cell their blood cells would be crescent shaped.  Sickle cell is caused by malformed hemoglobin called [...]

As a half Japanese and half Irish mixture, I was curious as to how Asians and also some Irish people get what is known as the “Asian flush” or “blush”.  This flush is basically the reddening of cheeks/face typically from consuming alcohol.  Both my parents, one who is Caucasian and one who is Asian get [...]
