How do twins happen? Fraternal vs. Identical

Answers

Answer:

Fraternal - 2 egg cells

Identical - split of zygote

Explanation:

Fraternal twins are likely to be formed by 2 different egg cells being simultaneously sent by the ovaries and both of them being fertilized by the sperm cells. They are non-identical because the DNA of the 2 egg cells and the 2 sperm cells are different.

Identical twins are formed after a single egg cell has been fertilized by a single sperm cell, then split after the first division. This results in 2 genetically identical embryos because they were formed from the same fertilized egg.

Answer: fraternal twins happen when superset sperms enter separate eggs but they fertilize together. Identical happen when the fertilized egg divided in two while it is still a tiny collection of cells. The sled contained halves then develop into two babies with the same genetic information.

A more recent system seeks to stimulate performing jitters.

The maturity of spinal cord injuries are caused by a quick, severe blow to the chines. The spinal cord and its jitters are also damaged as a result of the shattered( broken) bones. An injury can completely ramify or resolve the spinal cord in rare situations.

Why do I have ADHD? What caused me to have this disorder?

Answers

Answer:

Scientists are studying cause(s) and risk factors in an effort to find better ways to manage and reduce the chances of a person having ADHD. The cause(s) and risk factors for ADHD are unknown, but current research shows that genetics plays an important role. Recent studies of twins link genes with ADHD.1

In addition to genetics, scientists are studying other possible causes and risk factors including:

Brain injury

Exposure to environmental (e.g., lead) during pregnancy or at a young age

Alcohol and tobacco use during pregnancy

Premature delivery

Low birth weight

Research does not support the popularly held views that ADHD is caused by eating too much sugar, watching too much television, parenting, or social and environmental factors such as poverty or family chaos. Of course, many things, including these, might make symptoms worse, especially in certain people. But the evidence is not strong enough to conclude that they are the main causes of ADHD.
