How can non identical twin lambs be formed?
Non-identical twin lambs are formed when a ewe releases multiple eggs during ovulation and both eggs are fertilized by different sperm. This results in two separate embryos developing concurrently, each with its own genetic makeup, leading to the birth of non-identical twins.
How do you get identical and non identical twins?
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
How are twins born non-identical?
Non-identical (fraternal) twins are born when two separate eggs are fertilized by two separate sperm. This results in siblings with different genetic makeups and physical characteristics. Non-identical twins can be the same sex or different sexes.
Do identical or non-identical twins share a placenta?
do identical or non identical twins share the same placenta
Why are identical twins and fraternal twins not the exact same?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
What is the genetic difference between identical and non identical twins?
Identical twins are formed by the separation of the same embryo containing same genetic coding. thus the the twins are identical as formed from the same embryo. But this is not the case in the non-identical twins as they are formed from the individual embro each having different genetic coding.
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.
How does the development of placenta differ in identical twins compared to non-identical twins?
In identical twins, the development of the placenta is usually shared, meaning they both share one placenta. In non-identical twins, each twin typically has their own separate placenta.
What is the difference between idetical and non idetical twins in the way they are found?
The difference between Identical and Non-Identical twins is that Identical twins share the same placenta and are basically identical to one another. Non-Identical twins do not share the same placenta in the womb and two eggs fertilized at time of conception as opposed to one egg splitting in the case of Identical twins. I think that covers the basics. Hope this has clarified things for you.
A zygote that separates into two clusters of cells insted of just one prduce?
Non identical twins.
How can non identical sheep twins form?
Non-identical twins are when 2 sperm cells fertilize two different eggs during the same pregnancy.
What is The scientific name for identical twins.?
Identical twins (monozygotic) occur when a single egg, fertilized by a single sperm, splits into two identical halves. Two separate babies with identical DNA are formed. Identical twins are always the same sex and blood type. http://www.twin-pregnancy-and-beyond.com/identical-twins-or-fraternal-twins.html
