How genetic diseases affect the baby? Genes influence on children

First moments of life, a common genetic and environmental interactions shape the baby. Children can inherit many features of parents, which may further said, shaping and even affected by the environment of silence.
What is a genetic disease?
A genetic disease is a disease caused by the human DNA abnormalities. The exception may be as small as only one gene, or they may involve the addition or subtraction of the chromosome. Some of the genetic disease is directly inherited from the parents, while other diseases may result from genetic mutations or altered gene or a group of existing genes.
Gene mutations can lead to hereditary diseases or characteristics change. These mutations by exposure to hazardous chemicals or radiation, such as smoking, alcohol and other chemicals caused. It can also occur when the failure of cell division, DNA. Mutation may be neutral and have no effect, you can also increase the protein and protein beneficial or damage caused by the disease.
What are the different types of inheritance?
The genetic disease can be divided into four groups, single-gene disorders, chromosomal abnormalities, mitochondrial disorders and multifactorial disorders.
Single gene is also called single-gene inheritance. This type of inheritance are caused by variations or mutations in a single gene. There are more than 6,000 known single-gene, which is very common. Examples of single-gene disorders, including cystic fibroids, anemia, Marfan syndrome, Huntington's disease and hemochromatosis
Is a complex multifactorial genetic inheritance. The disease is caused by a combination of multiple genes or environmental changes caused by mutations. Examples of such multiple genetic factors, including hypertension, heart disease, Alzheimer's disease, arthritis, obesity, diabetes and cancer. Multifactorial genetic fingerprint patterns can also depicted, height, eye and skin color genetic traits like.
Mitochondria are inherited mitochondrial mutations, which are involved in cell respiration organelle small round or rod caused. Mitochondrial DNA is always inherited from the female parent. Examples of mitochondrial diseases, including diseases of the eye called the optic atrophy, a form of epilepsy and a class of dementia.
Chromosomal abnormalities, the cause of a chromosomal abnormality by the problem that the set of conditions are 23 pairs of chromosomes in cells containing the gene structure of an organism. A chromosome from the male and the female from each other to form a pair of chromosomes. Chromosomal abnormalities can affect any one or number of chromosomes. Chromosomal abnormalities can cause some unusual usually birth defects or death of the baby before birth.
Genes influence on children
It is composed of DNA and the basic physical and functional unit of heredity. There are over 2 million genes in the human body. There are two copies of each gene in each person - one from the mother and one from the father. Most people have the same type of genes, but there are a few genes are different in different people. These different genes to human small unique physical properties.
Sometimes, the children look like their parents or siblings, and sometimes they do not have any similarity with any person in the family. The children share their DNA with 50 percent of father and mother, so there is enough space for change.
Some surprising facts about human DNA.
Red hair is controlled by a single gene trait one of several;
Expression can be hereditary. One study showed that people who are born blind are much concentration, anger, disgust, joy, surprise, sadness is more likely accurate facial expressions. The results showed that the genetic link, because a blind person can not learn by watching others expressions.
Hair loss can be inherited from parents. Multiple genes from the father and mother can play the role of hair loss.
Simple genetic traits, such as the tongue, dimples, cleft chin is inherited from either parent roll.
Personality traits, social behavior, intelligence and other characteristics is that it is affected by many genetic and environmental factors of complex traits. Participating in the construction of these traits multiple genes. Genetic traits can not be separated from environmental factors, but genes play a personality, behavior and human intelligence development crucial role. It is also difficult to identify these genes.
