Monozygotic twins are two offspring that have identical DNA. This is because they arose from one zygote (hence monozygotic). Both of the offspring came from this zygote which at a particular time spilt. After the split, each individual had a copy of the original DNA

Are monozygotic twins opposite sex?
No, monozygotic twins would be the same sex. Monozygotic twins come from one single fertilized egg, or zygote, which then splits to create two separate zygotes which will be genetically identical, or "identical twins", which will always be of the same gender.
Can you have the same genotype but different phenotype?
yes
Are phenotype and genotype traits the same?
Phenotype and genotype traits don't always have to be the same. Phenotype is the physical characteristics and genotype is the genetic makeup. For example a pea plant can have the genotype of TT and look tall while another plant can have a genotype of Tt and also look tall (T= dominant trait; t= recessive trait.)
What phenotype is produced byBB?
The phenotype is the physical/observable trait of the animal - therefore the phenotype of this rabbit is black fur.The genotype, Bb, makes this rabbit heterozygous.
How do you determine a phenotype when the genotype is different but the phenotype is the same?
You look at the offspring. Offspring of a heterogenous match are going to have different phenotype percentages than those of a homogenous match.
Can two brothers with same genotype and blood group share the same DNA lab test?
Only identical twins from the splitting of the single ovum ( monozygotic) have identical DNA
Are monozygotic twins opposite sex?
No, monozygotic twins would be the same sex. Monozygotic twins come from one single fertilized egg, or zygote, which then splits to create two separate zygotes which will be genetically identical, or "identical twins", which will always be of the same gender.
What are the chances of albinism in monozygotic twins?
same as rest of population
Whom are considered monozygotic twins?
Monozygotic twins are also known as identical twins. They form from a single egg that splits into two forming two babies with the same genetic information.
Can you have the same genotype but different phenotype?
yes
What was the genotype of the offspring that did not share the parent's phenotype?
The genotype of the offspring that had the same phenotype as the parents is rr or wrinkled. The phenotype for the seed shape of both parent plants is round.
Are phenotype and genotype traits the same?
Phenotype and genotype traits don't always have to be the same. Phenotype is the physical characteristics and genotype is the genetic makeup. For example a pea plant can have the genotype of TT and look tall while another plant can have a genotype of Tt and also look tall (T= dominant trait; t= recessive trait.)
What is it call when twins are fertilized into two separate cells?
Dizygotic twins. If they were fertilized in the same egg, they would be called monozygotic twins.
What is the difference between dizygotic twins and monozygotic twins?
Dizygotic twins develop from two separate ova fertilized by different sperm at roughly the same time, they are also called fraternal twins. Monozygotic twins develop from one zygote that splits apart producing genetically identical zygotes; also called identical twins.
What was the genotype of the offspring the did not share the parents' phenotype?
If both parents have the same phenotype, but the offspring did not share that phenotype, then it is likely that the parents have a dominant phenotype, but the offspring has a recessive phenotype, which means that the offpring's genotype would be homozygous recessive, and it's parents' genotypes would be heterozygous. For example, the parents may both have the genotype Bb, which gives them black fur. Approximately 25% of their offspring should have the genotype bb, which gives them the phenotype of white fur.
Can 2 organisms have different genotypes but the same phenotype?
No. It is possible for the reverse to be true, two organisms can have the same phenotype but a different genotype. This is because the phenotype is what you will see on the outside whereas the genotype is the combination of alleles and since this determines the phenotype, two organisms with the same genotype will have the same phenotype. So, basically, no. Actually 2 organisms can certainly have different phenotypes with the same genotype--this refers to the concept of penetrance. Some people can have the gene for a condition but never show symptoms. An excellent example of this is the disease neurofibromatosis. This disease has very variable penetrance in which a child of an affected parent may show no signs of the disease, but then have a child with a severe form.
What is another name for material twins come from the same zygote so they have identical DNA?
Monozygotic
