No. In order for them to be identical they needed to start off as the same cell and divide so at first their DNA is identical meaning they have the same sex. During development slight changes may occur but the sex always stays the same. Boy-girl twins are always two different cells meaning that they are not identical. The term for boy-girl twins is furturnal. You can however have boy-boy twins and girl-girl twins that are not identical and they are also called furternal. So basically, identical twins start off as one cell that divides and furternal are two individual cells.
There is polar body twinning, that's when the egg splits before fertilization, and that can cause a male and a female. This is called semi identical twins or half twins. They share 75% of their genetic markers.
What else can I help you with?
Are there two animals that look exactly the same?
people do look the same but we all have a least one characteristic that makes us different. DNA is so complex and everyones is different. so really no two people can look EXACTLY the same but they can look similar only exception is twins
Can brother and sister dogs breed?
Yes, brother and sister dogs can breed and produce offspring. However, it is generally not recommended due to the increased risk of genetic diseases and abnormalities in the offspring resulting from inbreeding. It is best to avoid breeding close relatives in order to maintain genetic diversity and ensure the health of the puppies.
How many calvings can one cow have?
A cow will only calve once a year, and only give birth to one calf (twins 1:1000 births) at a time.
Can horses give birth to twins?
Yes, horses can give birth to twins, although it is rare. Twins can occur when the mare releases multiple eggs during ovulation, which are then fertilized by separate sperm. Twin pregnancies in horses can be risky due to complications such as developmental abnormalities and pregnancy loss.
Who sang everybody's talking at me featured in only fools and horses jolly boys outing?
The song "Everybody's Talkin'" featured in the Only Fools and Horses episode "Jolly Boys' Outing" was performed by Harry Nilsson.
How many ova needs to be fertlized in quadruplets 2 boys 2 girls?
It depends on if the boys and/or girls are identitical. If the boys AND girls are identical than only 2 ova would have been fertilized. If just the boys or girls are identical and the other 'set' is not than 3 ova would have been fertilized. If none are identical, than 4 ova would have been fertilized.

Does my sister have the same DNA as me?
Only if you are identical twins.
How many zygotes are used to form identical twins?
Identical twins develop from a single zygote that splits into two embryos during early development. Therefore, only one zygote is needed to form identical twins.
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.
What are the chances of identical twins having twins themselves?
Women who are themselves fraternal twins have a 10% chance of producing twins, identical twin women have only a 0.6% probability of having a twin birth.
What is the different between identical twins and franternal twins?
The DNA of identical twins and of clones is, apart from random, environmentally produced mutations, 100% identical. The only difference is that clones are produced on purpose through advanced bioengineering techniques while identical twins happen as an accident of nature. Identical twins are, in a sense, natural clones.
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.

Why are some twins identical and some not?
The reason why some twins are identical and some are not starts in utero. Identical twins occur when one egg is fertilized and it splits to create two embryos. Nonidentical twins come from different fertilized eggs.
Why must any differences between identical twins be controlled only by the environment?
Identical twins have the same DNA - meaning that without the effects of environment they would be identical in every single way.
How do you know if two twins are identical or just fraternal twins that look a lot alike?
(Person that asked the question)-Once twins are born, and old enough to determine whether they are identical or fraternal, how do you know if they are identical, or just fraternal twins that look identical? I was just curious.
