Two Headed Calf

In Alexandria, Egypt, a farmer said his cow has given birth to a two headed calf. It was difficult to take the calf out of its mother. After more than two hours, the calf was born with its leg injured. The calf survived but its too weak to stand up on its legs. The calf is feed by a bottle with its mother's milk. The calf's two head has its own facial features. In Egypt, this two headed calf is worth a lot of money. Most of the two headed cow has its two head connected to its neck. But this cow has two head and two neck which is consider to be rare.
This article relates to biology concepts because it is an example of mutation. Mutation is a change in the nucleotide sequence of a DNA. There are four basic types of mutations. They are substitution, insertion, deletion, and frameshift mutation. Substitution is when one nucleotide change with another. Insertion is when a extra nucleotide is added to the new DNA. Deletion is when one section of the DNA is deleted or lost. Frameshift is when one nucleotide is added or removed from the strand of DNA. There are different causes of mutation. Some of them are when the DNA replication has an error. This causes a small difference from its original copy of DNA. Another cause of mutation is from chemicals or radiation. The effects of mutations can be harmful or it may be helpful to the organism. Some mutation is pasted on from generation to generation from your parents. You might get a disease that is pasted on like sickle cell anemia.
We care because many people wants to find out why this happens. It may even happen to other organisms if it did to this one. Mutation is happening everywhere and the rate of mutation is happening faster then from before. We also care because we might find a cure for the mutation and how to reduce the severity of it. If the mutation is helpful, we might use this to our advantage and prevent the kind of mutation from happening.
