Every person on the planet has a DNA makeup that is unique. Understanding the connection between this genetic network and your heredity can reveal exciting and useful revelations. It’s no wonder DNA testing is all the rage these days. The following is a helpful guide on understanding DNA heredity.

Genes

These strands of DNA are housed in cells and have the role of making proteins. Each protein in the body has a designated function. Human cells contain approximately 25,000 genes. There are two types of genes you inherit from your parents: dominant and recessive. The dominant version determines things like eye and hair color. If both genes produce two different colors, the recessive gene is likely to be the combination of the two shades.

DNA testingChromosomes

DNA testing also involves examining your chromosome makeup. Under a microscope, they resemble threads, which are found in the nucleus of cells. Chromosomes are also composed of proteins and a DNA molecule. Their primary role is to ensure DNA provides exact copies during cell production. If replications are not accurate, certain cancers and other medical conditions may result. Like genes, chromosomes are passed down to you from your parents.

Dominant Alleles

Scientists classify a dominant allele as another gene variation. What makes it dominant is that one version of the allele has a certain amount of enzymes to supply cells to produce features such as eye color. Some of our physical traits may not need any enzymes to power cell production and create them. DNA testing specialists say dominant alleles also follow the pattern of genes and chromosomes — they’re inherited from your parents.

Meiosis

This process occurs when a cell divides, halving the number of chromosomes and creating genetically distinct versions from the parent cells. For the male sperm and female egg to combine, meiosis must take place. When the two come together to form a single cell, the result is typically an equal number of chromosomes in the fetus.
