Twins are caused on one of two conditions.
The first possibility is that two eggs were released from the mother and both were fertilized. The second possibility is that one egg was penetrated simultaneously by two sperm.
Yes, in both cases.The mutation causes both of the identical twins to look different from the rest of the family.The mutation causes one of the identical twins to look different from the other twin. That is, the mutation happened shortly after the cells that gave rise to both twins divided.
When a single egg is fertilized by a single sperm and then splits into two separate embryos, identical twins are formed. This process is known as monozygotic twinning and typically occurs during the earliest stages of embryo development. Twins resulting from this process will share the same genetic material and be of the same sex.
Yes, non-identical twins are often referred to as fraternal twins. These twins develop from two separate eggs fertilized by two different sperm cells, resulting in genetic differences that can make them look less alike than identical twins.
Two lots of twins are commonly referred to as two sets of twins.
Another name for maternal twins is identical twins. Maternal twins come from a single fertilized egg that splits into two, resulting in two babies with the same genetic makeup.
A female mammal causes twins.
No. Twins are determined by the cow herself, not the bull. It's still unclear as to what causes the act of twinning, even in humans.
Its at 50/50 chance... The twin or female double egg is what causes twins... its on the woman's side of the family..
Every sibling will loook different unless they are identical twins

Most likely not, as it shows to skip a generation. It skipped your grandma, so by logic, the pattern is yes-no-yes-no. You would the the fourth no. It will also depend on which side of the family the twins were on. The propensity to have fraternal twins can be inherited as a female trait that causes more than one egg to be dropped at a time. Identical twins have no genetic relationship that has been found to date.

identical twins are single egg twins. fraternal twins a two egg twins. fraternal
There is Identical twins, Nonidentical twins and Conjoined twins.
At the end of Chapter 20 in "The Giver," it is revealed that Jonas's father is responsible for the release of twins, which involves euthanizing one of the twins. This revelation shocks Jonas and causes him to question the society he lives in.
Yes they are twins. They are monozygotic twins (identical twins).
There are two types of twins. Fraternal twins are produced when two eggs are released and two separate sperm fertilize them. These twins are not identical, although they may still look alike because they are siblings.Identical twins are produced when one egg is fertilized by one sperm. During the zygote stage, the egg splits into two. This creates two separate embryos and thus the children will be identical copies of each other. The same exact chromosome match.
