Why can fraternal twins de different sexes while identical twins cannot?
To keep it simple and not get too technical, fraternal twins are from two eggs and two sperm that independently combine to produce a baby. Identical twins come from a single egg and sperm that divide to create two separate children. Gender is controlled by the males sperm and whether it contains the male genetic X chromosome. Since identical twins have the same sperm their genetic makeup is exactly the same (same egg and sperm used in development). Fraternal twins have two separate sperm and therefore it is possible one has the X chromosome and other does not.
What percent of genetic makeup is shared by identical twins?
100%Identical twins develop from the same egg, so have the same DNA. The only thing different between identical twins is finger prints, and retinal patterns.
Is gentic makeup probability?
There is no such thing as "gentic makeup". Perhaps you mean genetic, instead. There is a probabilistic element in genetic make up, but in some cases the probabilistic bit is overridden by recessive genes.
If both of a child's parents have a widow's peak will that child genetically inherit the widow's peak?
its likely but might not the chances of the shild not having a widows peak are 1/16 you can better know these odds if you know the parents genotype or genetic makeup.

Was Esau and Jacob identical twins?
No, Esau and Jacob were not identical twins. They were fraternal twins, meaning they were born from the same pregnancy but did not have the same genetic makeup.
Compared to frateral twins identical twins are much more similar in extraversion or neuroticism?
Identical twins are much more similar in both extraversion and neuroticism compared to fraternal twins. This suggests a higher genetic contribution to these traits in identical twins due to their identical genetic makeup, whereas fraternal twins share only about 50% of their genetic material on average.
Is farternal the same as identical?
No, fraternal twins come from two separate eggs fertilized by two different sperm, resulting in genetic variation, whereas identical twins come from the same fertilized egg, resulting in identical genetic makeup.
Are identical twins more common than fraternal twins?
No, fraternal twins are more common than identical twins. Identical twins occur when a fertilized egg splits into two embryos, resulting in two individuals with the same genetic makeup. Fraternal twins occur when two eggs are fertilized by two different sperm, resulting in siblings who share approximately 50% of their genetic material, like regular siblings.
Is the genetic makeup of daughter cells unique or identical to other cells in the organism during mitosis?
The genetic makeup of daughter cells in mitosis is identical to each other and to the parent cell. Mitosis is a form of cell division where the resulting daughter cells have the same genetic information as the original cell.

If two animals have the same genes then are they the same family order class phylum and kingdom?
If their genetic makeup is identical then they are identical twins.
Are the genetic makeup the same for first cousins and siblings?
No. Except for identical twins, the genetic makeup of each person is different. However, the more closely related you are to someone, the more similar your genetic makeup. So the genetics of siblings is more similar than of first cousins.
Are Brittany and Cynthia Daniel identical twins or fraternal twins because they look a bit different from one another?
Brittany and Cynthia Daniel are identical twins. Even though they may appear to look slightly different due to factors such as hairstyles, makeup, and individual characteristics, they share identical DNA as they originated from the same fertilized egg.
Which set of subjects would share the most genetic heredity?
Identical twins would share the most genetic heredity, as they result from a single fertilized egg splitting into two embryos. Therefore, they have almost identical genetic makeup.
What is the genetic makeup of the final product of mitosis?
Mitosis produces two genetically identical daughter cells which are diploid (2n), meaning that they have two sets of homologous chromosomes (chromosomes with genes for the same characteristics).
Is the DNA between brothers different?
Generally, each person has his or her own genetic makeup. Identical twins can have a very similar DNA>
