Congenital disorder involves defects in or damage to a developing fetus A fetus is a developing mammal or other viviparous vertebrate after the embryonic stage and before birth. The plural is fetuses. It may be the result of genetic Genetics , a discipline of biology, is the science of heredity and variation in living organisms. The fact that living things inherit traits from their parents has been used since prehistoric times to improve crop plants and animals through selective breeding. However, the modern science of genetics, which seeks to understand the process of abnormalities, the intrauterine (uterus The uterus is a major female hormone-responsive reproductive sex organ of most mammals, including humans. It is within the uterus that the fetus develops during gestation. The term uterus is used consistently within the medical and related professions; the Germanic term, womb is more common in everyday usage. The plural of uterus is uteruses or) environment, errors of morphogenesis Morphogenesis , is the biological process that causes an organism to develop its shape. It is one of three fundamental aspects of developmental biology along with the control of cell growth and cellular differentiation. The process controls the organized spatial distribution of cells during the embryonic development of an organism. Morphogenetic, or a chromosomal A chromosome is an organized structure of DNA and protein that is found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions. The word chromosome comes from the Greek χρῶμα abnormality. The outcome of the disorder will further depend on complex interactions between the pre-natal Pregnancy is the carrying of one or more offspring, known as a fetus or embryo, inside the uterus of a female. In a pregnancy, there can be multiple gestations, as in the case of twins or triplets. Human pregnancy is the most studied of all mammalian pregnancies. Obstetrics is the surgical field that studies and cares for high risk pregnancy deficit and the post-natal Postnatal is the period beginning immediately after the birth of a child and extending for about six weeks. Another[citation needed] term would be postpartum period, as it refers to the mother (whereas postnatal refers to the infant). Less frequently used is puerperium environment.[1] Congenital disorders vary widely in causation and abnormalities. Any substance that causes birth defects is known as a teratogen Teratology is the study of abnormalities of physiological development. It is often thought of as the study of birth defects, but it is much broader than that, taking in other developmental stages, such as puberty; and other life forms, such as plants. The older term congenital [1] disorder does not necessarily refer to a genetic disorder A genetic disorder is an illness caused by abnormalities in genes or chromosomes. While some diseases, such as cancer, are due in part to a genetic disorders, they can also be caused by environmental factors. Most disorders are quite rare and affect one person in every several thousands or millions. Some types of recessive gene disorders confer an despite the similarity of the words.
