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 are the similarities between fraternal twins?
Fraternal twins, or dizygotic twins, share about 50% of their genetic material, similar to regular siblings, as they are formed from two separate eggs fertilized by two different sperm cells. They often have similar physical traits, such as hair color and eye color, but can also exhibit significant differences in appearance and personality. Both twins typically grow up in the same environment, which can influence their interests and behaviors, leading to shared experiences and bonds. However, unlike identical twins, fraternal twins do not share the same genetic makeup and may not have the same level of resemblance.
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.
How do the inherited and acquired traits of identical twins differ from those of fraternal twins?
Identical twins share 100% of their genetic makeup, leading to very similar inherited traits, such as physical appearance and certain health predispositions. In contrast, fraternal twins, who arise from two separate eggs fertilized by different sperm, share about 50% of their genetic material, resulting in more variability in their inherited traits. Acquired traits, influenced by environment and experiences, can differ significantly in both types of twins, as they may have unique life experiences despite their genetic similarities. This means identical twins often exhibit more similar traits overall compared to fraternal twins.
Is Olly Murs' twin identical to him?
Olly Murs does not have an identical twin; he has a fraternal twin brother named Ben Murs. While they share similar features due to their familial relation, they are not identical twins, meaning they do not have the same genetic makeup. Fraternal twins can look quite different from each other, and this is the case with Olly and Ben.
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.
What are the key differences between monozygotic and dizygotic twins in terms of their genetic makeup and development?
Monozygotic twins, also known as identical twins, are formed from a single fertilized egg and share the same genetic makeup. Dizygotic twins, or fraternal twins, are formed from two separate eggs fertilized by two different sperm cells, resulting in different genetic makeup. Monozygotic twins are more similar in terms of genetic traits and development compared to dizygotic twins.
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.

Are the Gosselin sextuplits fraternal?
Yes, the Gosselin sextuplets are fraternal, meaning they were conceived from separate eggs fertilized by separate sperm cells. This results in each of the sextuplets having their own unique genetic makeup, which can lead to differing physical traits and personalities, unlike identical multiples that share the same genetic material. The sextuplets were born on May 10, 2004, to parents Jon and Kate Gosselin.
Are mullage twins?
Mullage twins, often referred to as "semi-identical twins," are a rare type of twins that occur when a single fertilized egg splits into two embryos but also shares some genetic material. This results in twins that are genetically similar like identical twins, but not completely identical. This phenomenon is extremely uncommon, and most twins are either fraternal (dizygotic) or identical (monozygotic). The unique genetic makeup of mullage twins can lead to interesting medical and biological implications.
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.
