Not always. Even identical twins will experience some differences in development before birth. However, it is unlikely that the shape of twins' ears would be radically different, even in most fraternal twins.
No. There are different kinds of twins. They can be identical or paternal. Paternal is when 2 eggs are fertilized and the babies grow in the same uterus but are not identical. An identical twin is formed when an egg is fertilized and then splits into two different babies.
I have twin daughters with whom I can easily distinguish their identities based solely on the sound of their voice. One has a more nasal quality.
However, I can easily tell them apart visually as well; whereas to others, "they look exactly the same". So, I suppose to many who are less familiar with my girls, perhaps they appear to have the same voice.
My opinion is NO everyone is made different . You may look like them but somewhere you are different from the other twin . Even if you are identical twins . God made EVERYONE different from the others you always are gonna have something different about you .
No. Identical twins are identical. Fraternal twins are not.
Yeah, actually I know 2 set of twins with different noses. Of course it's not really obvious.
They never are.
yes they do
Homozygous means "the same egg." That refers to identical twins. Identical twins are always the same gender since they have the same chromosomes.
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.
Yes. Conjoined twins are always identical (monozygotic) twins, and identical twins are always the same sex.There is a theoretical case where identical twins could be opposite genders, when the babies are female but in one of the females, a branch of one X chromosome breaks away; however, I don't believe this has ever been observed.
No, even though twins do have identical DNA, they can have far different environments and life experiences. So, two identical twins though genetically the same could be very dissimilar in intelligence.
Because the mother identical twins each have a different husband . . . half of his characteristics show up in their babies.
Twins are identical because they come from the same egg.
do identical or non identical twins share the same placenta
The same as when you had the first set of identical twins.
if they share 1 heart then yes they do. but if they have different hearts then they do not
identical twins do. just not the same fingerprints.
Identical twins.
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.
Homozygous means "the same egg." That refers to identical twins. Identical twins are always the same gender since they have the same chromosomes.
No. All identical twins are the same sex. Judith and Hamnet were opposite sexes, and so were fraternal twins.
fraternal twins have two different chromosomes
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.
