Identical twins, or monozygotic twins, originate from a single fertilized egg that splits into two embryos, resulting in nearly identical genetic material. However, despite their genetic similarities, environmental factors can lead to epigenetic changes that affect gene expression, meaning that their genes can function differently. Additionally, mutations can occur after the split, leading to slight genetic differences over time. This interplay of genetics and environment contributes to the unique traits and characteristics of each twin.
What else can I help you with?
What do identical twins have the same sat of?
They have the same set of chromosomes, which can be also stated as having the same set of genes.
Why are the identical twins different?
Because genes do not account for every trait or characteristic. Some characteristics are influenced by environment.
Why does identical twins not have the same weight and Skin colour?
Eye colour is caused by genetics whereas the weight of a person depends on how they life their life (how healthily they eat or how much exercise they do) so it is an environmental variation. Identical twins have the same genes so have the same eye colour.
Psychologists use what to determine the role that heredity and the environment play in determining trait?
Psychologists like to use sets of identical twins for studies. If the identical twins turn out more similar than fraternal twins or regular siblings, they conclude that the trait is genetically influenced and hereditary.
Can identical twins have different natural hair colours?
Identical twins will have the same color hair, as it grows form the scalp. But if one stands out in the sun, and the other does not, the hair of the one may be naturally lightened; there are other ways the hair color can be altered naturally.
What are two horses with identical genes called?
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
Identical twins have the same set of?
genes
Can genes of two persons be identical?
The genes of identical twins are identical because the twins come from one egg that has split after fertilization. Fraternal twins are not identical since they come from two eggs but have occupied the mother's womb at the same time.
Two horses with identical genes can be called?
Depending on how they got identical genes, they may be clones (if it was done artificially, and they were born at different times), or if they were born at the same time, they could be identical twins. However, I don't think horses ever have twins.
If two animals have the same genes then are they the same family order class phylum and kingdom?
If their genetic makeup is identical then they are identical twins.
Can anyone else have the same exact genes that you have?
Yes, identical twins are born with the same DNA.
What do identical twins have the same sat of?
They have the same set of chromosomes, which can be also stated as having the same set of genes.
Why do identical twins have the same genotype?
Identical twins have the same genotype because they have the exact same genes. Identical twins are formed when one fertilized egg (zygote) splits in two and each of the now two zygotes each develop into different beings. Identical twins are therefore referred to as monozyygotic twins and they have the same DNA.
What kinds of twins are there?
Identical and Fraternal There are identical and fraternal. Fraternal twins happen when 2 different embryos start growing at the same time, so you get a brother and a sister or 2 sisters or 2 brothers that are the same age. Identical twins happen when 1 embryo splits into 2 embryos when it is only a few cells big, so both babies have the same genes.
Why are the identical twins different?
Because genes do not account for every trait or characteristic. Some characteristics are influenced by environment.
Why does identical twins not have the same weight and Skin colour?
Eye colour is caused by genetics whereas the weight of a person depends on how they life their life (how healthily they eat or how much exercise they do) so it is an environmental variation. Identical twins have the same genes so have the same eye colour.
Why do scientist use studies of identical twins to learn about human characteristics?
Scientists use studies of identical twins because they share the same genetic makeup. By comparing identical twins with non-identical twins, researchers can separate the effects of genetics from environmental factors in order to understand how traits and characteristics are influenced by both nature and nurture. This can provide valuable insights into the role of genes in shaping human characteristics and behaviors.
