genetic defects are responsible for disorders can be on any chromosome wether it is and autosome or a sex chromosome.
Non-chromosomal congenital defects refer to conditions or abnormalities that are not caused by changes in the person's chromosomes. These defects can result from a variety of factors such as exposure to toxins, infections during pregnancy, or unknown genetic mutations.
Cells have 42 chromosomes, reproductive cells have 21. An extra chromosome is usually the cause of genetic defects.
Livestock themselves are unique in their own major types of abnormalities or mutations. But the causes of these abnormalities or mutations are very similar among all livestock species. Therefore, abnormalities and mutations in livestock are caused by four main things: Heredity Nutritional Deficiencies or Toxicities Radiation Accidents of Development
This type of error is known as a chromosomal abnormality, which can occur during cell division and lead to an incorrect number of chromosomes in the zygote. Such abnormalities often result in zygotes that either fail to develop to term or develop severe congenital defects. Common examples include conditions like Down syndrome, Turner syndrome, and Klinefelter syndrome, which can arise from these chromosomal issues.
well you see is when you have lake of chromezome you are not in the good and give to the poor for money if only you can show it for money so, when to tell you is then give me some for ill open it and show it okay
Genetic defects can be associated with autosome and chromosome abnormalities.
When a fertilized egg has defective autosomes, it often leads to developmental abnormalities or pregnancy loss. Such defects can result in conditions like Down syndrome or other genetic disorders, depending on the specific autosomes involved. In many cases, these abnormalities can cause the embryo to fail to develop properly, leading to miscarriage early in the pregnancy. Overall, the presence of defective autosomes significantly impacts the viability and health of the developing fetus.

A congenital defect is any abnormality that is caused by defects or damage in a developing fetus. Congenital defects can be caused by a number of things: defects in the fetus's genetic code, abnormalities in the fetus's chromosomes, the environment in the uterus, infection, or many other things. Examples of congenital defects include Down syndrome, cystic fibrosis, club foot, and albinism (being an albino).

Drugs such as LSD have been associated with arm and leg abnormalities and central nervous system problems in infants. Crack cocaine also has been associated with birth defects.it is hard to determine the effects of individual drugs.
Because if they have too much or too little chromosomes, they can have defects
Coloboma Heart defects Atresia of the choanae Retardation of growth and development Genital and urinary abnormalities Ear abnormalities and/or hearing loss
Klippel Feil syndrome can occur in association with scoliosis, spina bifida, cleft palate and defects involving the urinary tract, kidneys, heart, brain, and skeleton
Congenital defects in dogs are the abnormalities which are present at the time of birth. Congenital defects can occur in any system or in any part of the body.
Treatment depends on the type of birth defect and how serious it is.Some abnormalities can be corrected with surgery.Experimental procedures have been used successfully in correcting some defects.
