DNA

A Chromosone are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Genes live on Chromosones. An example of a Gene is Eye color. An Allele is the mutations of that Gene like blue or green eyes. A Genotype is the specific combination of Alleles a person has. If two people, one with blue eyes and one with brown eyes, have a baby that child will have a Genotype with two different Alleles. This type of Genotype with two different Alleles is called a Heterozygous Genotype. If the parents both had blue eye then the child would have a Homozygote Genotype, or a Genotype as a result of two of the same Alleles.

When an Allele is Dominant it tends to override the other Allele in a Heterozygous Genotype, when an Allele is Ressesive it tends to be the one overridden. While the Genotype is the actual genetic makeup of the person, their Phenotype is what it looks like they have. The Phenotype is dependant on the Dominant Allele. Because the Brown eye Allele is Dominant and the Blue eye Allele is Ressesive, the child mentioned above would have visibly Brown eyes. Their Phenotype would then be Brown eyes.
