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.
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.
Identical twins are more likely than the general population to share which of these disorders?
Identical twins are more likely to share genetic disorders such as Alzheimer's disease, autism, and bipolar disorder compared to the general population. This suggests a strong genetic component in these conditions.
Are twins in the same placenta genetically identical"?
No, twins in the same placenta are not genetically identical. While identical twins share the same DNA, they may have slight genetic differences due to mutations that occur after fertilization.
Who would show more concordance for a chiefly hereditary trait?
Identical twins would show more concordance for a chiefly hereditary trait compared to fraternal twins or siblings, as they share all of their genetic material. This higher genetic similarity increases the likelihood of both twins expressing the trait if it is primarily influenced by genetics.
Who would have the most genetic similarities identical twins or fraternal twins?
Identical twins would have the most genetic similarities, since they share the same original 46 chromosomes.
How much genetic material to fraternal twins share?
Fraternal twins share about 50% of their genetic material, just like any other siblings. They develop from two separate eggs fertilized by two different sperm.
Which set of subjects would share the most genetic heredity?
identical twins raised in different cultures

Why do twins look alike?
Twins look alike because the foetus splits in two inside the mother's womb. Therefore, both babies share the exact same genetic information (because the genetic information determining what they would look like was transferred when they were joined as one), but are two individual people.
Why do you think identical twins were more alike than fraternal twins?
Fraternal twins share most of their genetic material, by virtue of having the same parents. Identical twins, however, by definition share 100% of their DNA. This means, for example, that identical twins cannot ever be one of each gender, as fraternal twins often are.
Identical twins are more likely than the general population to share which of these disorders?
Identical twins are more likely to share genetic disorders such as Alzheimer's disease, autism, and bipolar disorder compared to the general population. This suggests a strong genetic component in these conditions.
Are twins in the same placenta genetically identical"?
No, twins in the same placenta are not genetically identical. While identical twins share the same DNA, they may have slight genetic differences due to mutations that occur after fertilization.
Which set of subjects would share the most similar genetic heredity?
identical twins raised in different cultures, haploid plants made diploid by colchicine also share similar genetic heredity.
Who would show more concordance for a chiefly hereditary trait?
Identical twins would show more concordance for a chiefly hereditary trait compared to fraternal twins or siblings, as they share all of their genetic material. This higher genetic similarity increases the likelihood of both twins expressing the trait if it is primarily influenced by genetics.
Do identical twins share same interest?
Identical twins may share similar interests due to their genetic makeup and shared environment. However, they are still individuals with unique preferences and personalities, so it is not guaranteed that they will have all the same interests.
