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.
What is the difference between dizygotic twins and monozygotic twins?
Dizygotic twins develop from two separate ova fertilized by different sperm at roughly the same time, they are also called fraternal twins. Monozygotic twins develop from one zygote that splits apart producing genetically identical zygotes; also called identical twins.
Do monozygotic twins share a placenta?
Yes, monozygotic twins can share a placenta if they implant close enough to each other in the uterus.
What percentage of twins are identical?
Approximately 30 of twins are identical, also known as monozygotic twins.
What occurs when there is a failure in the separation process of identical twins before the thirteenth day after fertilization?
If there is a failure in the separation process of identical twins before the thirteenth day after fertilization, it can result in conjoined twins. Conjoined twins occur when the developing embryos do not fully separate and remain connected, sharing certain organs or body parts.
What is the frequency of monozygotic twins versus dizygotic twins?
The frequency of having monozygotic twins (identcal) is about 4 out of every 1000 births. Whereas dizygotic twins (fraternal) is about 12 out of every 1000.
What is the frequency of monozygotic twins versus dizygotic twins following IVF?
The type of twins created following IVF are Dizygotic. These are twins resulting from the fertilisation of two separate eggs by two separate sperm. Monozygotic twins are the result of a single egg dividing after fertilisation. http://twinstips.com

What is it call when twins are fertilized into two separate cells?
Dizygotic twins. If they were fertilized in the same egg, they would be called monozygotic twins.
How may types of twins are there and which type may have different sex?
There are two types of twins -- monozygotic ("identical") from a single egg, and dizygotic (fraternal) from two eggs. Only dizygotic twins can have a different sex.
What The scientific name for fraternal twins.?
Identical twins are called monozygotic. Fraternal twins are called dizygotic.
Twins who delevelop in separate amniotic sacs?
Twins who develop in separate amniotic sacs are known as dizygotic or fraternal twins. This means they were conceived from two separate eggs fertilized by two different sperm cells. Dizygotic twins can have different genetic makeup and are no more similar than siblings born at different times.
How do dizygotic twins?
Two separate eggs are fertilized. Dizygotic twins are the same as fraternal twins.
How many different kid of twins are there?
there are two types of twins-- fraternal and identical. Fraternal twins are genetically unique, and they usually have physical differences. Identical twins are identically identical, such as a clone, and have exact physcial characteristics, excluding weight and scars etc.
Can twins implant close together?
Yes, twins can implant close together in the uterus, particularly if they are conceived from a single fertilized egg that splits (monozygotic twins) or from two separate eggs (dizygotic twins). In cases of monozygotic twins, they may share the same placenta and can be very close in proximity during implantation. However, the exact spacing can vary based on factors like uterine environment and individual embryo development.
Do monozygotic twins have the same personality?
Monozygotic twins, also known as identical twins, often share similar personality traits due to their genetic makeup. However, they can still exhibit differences in personality influenced by environmental factors, individual experiences, and social interactions. While studies show a higher correlation in personality traits among monozygotic twins compared to dizygotic twins, they are not guaranteed to have the same personality. Thus, while they may have similarities, each twin can still develop a unique personality.
