What Is Genetics?
Genetics is the written report of genes. Our genes carry information that gets passed from ane generation to the side by side. For instance, genes are why one kid has blonde pilus like their mother, while their sibling has chocolate-brown hair like their father. Genes as well determine why some illnesses run in families and whether babies will be male or female person.
What Are Genes?
Genes are sections of Dna (deoxyribonucleic acid) that are found inside every human cell. They're and then tiny that they can be seen simply under a powerful microscope. DNA is made of iv chemicals that form pairs in different combinations. The combinations create codes for dissimilar genes. Each person has about twenty,000 genes. The genes code for different traits, such as eye color, body type, or male or female sex.
What Is a Chromosome?
Inside each jail cell, Dna is tightly wrapped together in structures chosen chromosomes. Every normal jail cell has 23 pairs of chromosomes (for a total of 46):
- 22 pairs of chromosomes are the same in males and females. These are chosen autosomes (AW-tuh-soamz).
- The 23rd pair — the sexual activity chromosomes — determines the sex activity of the babe. Females take two Ten chromosomes and males take one X chromosome and 1 Y chromosome.
How Do Genes Pass From Parent to Kid?
To course a fetus, an egg from the mother and sperm from the father come together. The egg and sperm each have 1 one-half of a fix of chromosomes. The egg and sperm together requite the infant the full set of chromosomes. And so, half the baby's DNA comes from the mother and half comes from the father.
What Is a Genetic Disorder?
A genetic disorder happens when a gene (or genes) has a trouble with its code, and this causes a wellness problem. Sometimes a genetic disorder happens when a kid inherits it from one or both parents. Other times, information technology happens only in the child (and the parents practice not have the genetic disorder).
How Practice Genetic Disorders Happen?
Unlike things can cause a genetic disorder, such every bit:
- a change (mutation) in 1 gene on a
- a missing office of a chromosome (called a deletion)
- genes shifting from ane chromosome to some other (called a translocation)
- an actress or missing chromosome
- too few or too many sex chromosomes
Looking Ahead
Scientists are learning more and more most genetics. A worldwide research project called The Human Genome Project created a map of all man genes. Information technology shows where the genes are located on the chromosomes. Doctors tin can use this map to find and treat or cure some kinds of genetic disorders. There is hope that treatments for many genetic disorders will exist adult in the time to come.
