Genes Biology Paper

Have you ever wondered about genes? Genes are fascinating and important in giving organisms traits. A trait is "a distinguishing quality or characteristic, typically one belonging to a person" (Merriam-Webster). There are many subtopics when discussing genes. Three of these subtopics are the definition of a gene, the heredity of a gene, and the classification of a gene.

Defining a gene is complex. "A gene is a section of DNA that codes for the production of a protein or a portion of protein, thereby causing a trait"(Wile Durnell 197). They are passed from a parent to the child, and they are found in the chromosomes of an organism (Ashg). There are

A gene's purpose is to make up human traits and to help make proteins. The genes are made of the four nucleotide bases: adenine, guanine, cytosine, and thymine. When organizing the nucleotide bases in different orders, the offspring receives different traits. However, organized adenine always connects with thymine and cytosine always with thymine (Med-news). People often breed organisms and plants to give them specific traits, such as larger crops, which give the genes another purpose (Ghr). A person only needs one copy of a dominant trait to receive it. However, the person would need two copies of a recessive trait to receive it

One method scientists use to organize traits is Punnett Squares. A Punnett Square is a visual way to see the dominant and recessive alleles. "A dominant allele is an allele that will determine the phenotype if just one is present in the genotype" (Wile Durnell 236). "A recessive allele is an allele that will not determine the phenotype unless the genotype is homozygous in that allele. A simple two by two Punnett Square will have one parents genotype on the top and the other parents on the side. When combined, the two will have a pattern which is the new possible genotype (Wile Durnell
