Why are the twins identical?
Twins are not necessarily identical. They can be fraternal as well. Identical twins result when one fertilized egg splits in two. Fraternal twins result from two fertilized eggs.
What is the difference btween identical twins and fraternal twins?
Identical twins are the result of a single fertilized embryo splitting in two at an early stage and forming two viable embryos. As such, identical twins have identical DNA. Fraternal twins are the result of two distinct fertilized embryos being viable. As such, they have different DNA. They could even be different sexes.
What is the difference between a fraternal twins and identical twins?
If two (or more) eggs are fertilised and develop together you will get fraternal twins. Identical twins are the result of a single fertilised egg dividing into two embryos.
Why identical twins are similar?
If they were not then they would not be called identical twins!
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 stage of asexual reproduction when the nucleus divides to form 2 genetically identical nucleus?
twins
What type of reproduction has occurred when one organism produces genetically identical offspring?
Asexual Reproduction Asexual reproduction is ONE parent giving rise to offspring with identical genome(s) as the parent Common Types of Asexual Reproduction: Fission (Mitosis in somatic cells) Budding (In Yeast, Hydra) Vegetative Propagation (aka Vegetative Reproduction) (Clonal colonies in trees) Fragmentation (In Fungi) BUT IF THE OFFSPRING HAVE THE SAME GENOME AS EACH OTHER BUT NOT THE SAME AS THE PARENT, then the offspring most likely started as one, but split, for example identical twins
Why are the twins identical?
Twins are not necessarily identical. They can be fraternal as well. Identical twins result when one fertilized egg splits in two. Fraternal twins result from two fertilized eggs.
What difference between sexual and asexual reproduction?
Sexual reproduction involves the fusion of specialized cells from two parents to produce offspring with genetic variation. Asexual reproduction involves the production of offspring from a single parent, resulting in genetically identical individuals. Sexual reproduction promotes diversity and adaptation to changing environments, while asexual reproduction is more efficient in favorable conditions.
What does genetically identical individuals mean?
Genetically identical individuals refer to organisms that have the same genetic makeup, typically arising from asexual reproduction or identical twinning. These individuals have identical sets of genes, making them clones of each other. Examples include identical twins and certain plant propagation methods like tissue culture.
What is the difference btween identical twins and fraternal twins?
Identical twins are the result of a single fertilized embryo splitting in two at an early stage and forming two viable embryos. As such, identical twins have identical DNA. Fraternal twins are the result of two distinct fertilized embryos being viable. As such, they have different DNA. They could even be different sexes.
Why can fraternal twins be different genders but identical twins are are the same gender?
Identical Twins are the result of a single fertilized egg spliting in two producing two genetically identical children. Fraternal twins are the result of the mother producing two eggs each fertilized by a different sperm from the father. This can result in opposite sex twins.
Are fraternal twins technically clones?
No, fraternal twins are not clones. Fraternal twins occur when two separate eggs are fertilized by two separate sperm, resulting in two genetically unique individuals. Clones are genetically identical individuals created through asexual reproduction or artificial techniques like somatic cell nuclear transfer.
What is the difference between a fraternal twins and identical twins?
If two (or more) eggs are fertilised and develop together you will get fraternal twins. Identical twins are the result of a single fertilised egg dividing into two embryos.
What do twins have in common?
Identical twins are identical because they both came from the same egg. The term "Identical" is used as they look very much like each other and anybody can say that they are twins by just looking at them.
Are there people with identical DNA aside from identical twins?
No, due to the random combination of genetic material during sexual reproduction, it is extremely rare for two individuals to have identical DNA. Identical twins are the only naturally occurring individuals who have the same DNA.
Why are identical twins identical and fraternal twins are not?
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.
