Best Answer

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.

What happens when breeders cross two genetically identical organisms?

When breeders cross two genetically identical organisms the same genes have an increased chance of expressing themselves in the offspring. However, the offspring will also have genes from ancestors.


Two horses with identical genes can be called what?

Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.

What is the genetic difference between identical and non identical twins?

identical twins have the same genes from the same parents. Non identical twins have different genes.


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.


What is the term used to describe two genes for a specific trait that are not identical?

Heterozygous.

a similar but not identical combination of genes.


With the exception of identical twins siblings who have the same two biological parents are likely to look similar but not identical to each other because they have?

Because they have similar, but not identical, combination of genes.

What can be concluded if the genes of two species are found to be nearly identical?

That they share a common ancestor.


Why do two nuclei in a divided cell need to be identical?

In a divided cell, the nuclei is identical because it can only reproduce "A sexually" in a sense. Meaning, that if offspring is reproduced, then it must have the genes of the parent cells, but if there is only one parent, then it will have only the exact genes of the single parents, there by being identical.


Do twins have identical genes but different chromosomes?

Identical twins have identical chromosomes with identical genes.Non-identical twins have similar chromosomes but some genes differ between the two people.All people have the same sets of chromosomes (barring occasional anomalies). The reason identical (monozygotic) twins have the same genes is that they started life as one fertilized egg (zygote), which began to divide to form one embryo, but subsequently split into two, each of which formed a complete human being.So the cells of identical twins are as alike as the cells of your arm and leg; they come from the same sperm and egg.Non-identical (dizygotic or fraternal) twins developed from two different zygotes, that formed when two genetically different sperms fertilized two genetically different ova that happened both to be mature at the same time. Non-identical twins are no more alike genetically than any other siblings (brothers and sisters).


What does genetically identical mean?

i think it means to have identical genes the same genes as it's parent's cell'si've only heard that term when i was studying mitosis, which is the process of cell divisionand when a cell divides, the two daughter cells are genetically identical.hope that helps


If identical brothers impregnated identical sisters would the babies be identical cousins?

No, because not all genes are selected from the parents. Identical brothers/sisters have exactly the same genes...the egg split just after genes were selected. They will sure look similar, though.


How similar are two people with respect to chromosomes genes and alleles?

No two people in the world are exactly the same except identical twins. Their chromosomes are exactly the same because the egg split in two and formed two identical embryos.


Is tt a homozygous recessive genotype?

Yes.A homozygous genotype is a gene with two identical alleles. Recessive genes are represented by a lowercase letter. Thus, a homozygous recessive genotype would be two identical genes with lowercase letters.


How do you use monohybrid in a sentence?

Can two people ever be exactly the same?

As people are a product of their genes and their environment, and as there is virtually no case where genes and environment are identical (even for twins), the odds are that no, no two people could ever be exactly the same.


Why all offspring produced through asexual reproduction are identical?

Asexual reproduction replicates only the genes of the original cell, which splits to produce two virtually identical cells.


What is the difference between homozygote-and-heterozygote?

The difference between the two is that a homozygote is an organism that has two identical genes at the same place on two corresponding chromosomes and a heterozygote desribes a cell or orangism that has two or more different versions of alleles of at least one of its genes


Do identical twins shrare only about half their genes?

Identical twins have the same 26 genes. Genetically they are the same, although there is a chance that they can have different features.


What is hetrozygous and homozygous?

homozygous having a pair of identical genes (TT or tt) hetrozygous having a pair of non-identical genes (Tt)


Why do identical twins have the same geneotype?

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.
