First of all, there is no 'twin gene' as such. The only genetic link to twinning is that of hyper-ovulation, in which the mother releases more than one egg at a time. If women in a particular family have the gene for hyper-ovulation then this will increase their chances of having dizygotic (non-identical) twins. There is no link between genes and identical twinning.
There is no scientific evidence to show that twins are more likely to skip a generation, although if hyper-ovulation runs in a family then it is more likely that twinning will occur across the different generations.

Why do some traits skip a generation?
I like puppies :) Traits 'skip' generations precisely because most traits are not accounted for by a single gene, but by their combination with other genes. There is no brown hair gene, or blue eye gene. These traits may be controlled by recessive genes, so they seem to skip a generation from grandparent to you. For example, if a trait is produced by a recessive gene, one of your parents may be a carrier but not possess the trait (because she inherited a dominant gene that overrode the recessive one). However, when her genes were recombined to produce the ovum from which you grew, and when that combined with your father's DNA, the trait may resurface.
In Mendel's experiment why did traits show up in the f1 generation that were not present in the f1 generation?
the traits were recessive
Are many undesirable traits in humans recessive?
the term recessive traits referrs to genetics there are no bad traits recessive traits are the ones that are less likely to show up such as lleft handedness dominate traits are things like eye color,the color of your hair and skin etc
What genes are recessive traits?
These traits are called dominant traits. They will overcome the recessive gene and the dominant trait will be expressed. A recessive gene needs two alleles present in its genotype to be expressed.
What did Mendel call the observed trait and the trait that seemed to disappear?
he called the observed traits dominant and the disapear traits recessive.
Can recessive traits skip generations?
Your parental genotype. AA X Bb gives two--------AB two--------Ab The recessive trait is masked in this generation. This is how recessive traits skip generations
Dominant and recessive traits?
A dominant trait is a genetic trait which may cause a hereditary condition, a recessive trait disappears or goes in the background and only shows in a few generations.
Why your offsprings dont look exactly like you?
A child gets half of its DNA from each parent. This is why you can see characteristics of both parents in a child. --truckbroker-- More importantly, some traits are recessive in the parent. Or dominant in a dominant recessive trait. In which they may skip generations.

What inheriting traits?
traits passed down from parent to offspring but it may skip generations and that are improved through all the generations through the ages like birds and and other animals!
Why is ginger the only hair colour to skip generations?
Becasue red hair is caused by a recessive relatively rare gene.
Why are recessive disorders more common than dominant disorders?
dominant traits show up in the first generation so any disorders have a 50% percent chance of showing up in offspring. recessive traits skip a generation therefore any diseases would have on a 25% chance.
What is the difference dominant and recessive trait?
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
If Laurie has albinism but neither of her parents exhibits this inherited condition the trait must be?
Recessive. This trait can skip generations, because it requires two recessive alleles (ex. aa vs Aa), and can be present in heterogeneous alleles (Aa) without showing a recessive phenotype.
Two generation of severe inbreeding results in what?
Two generations of severe inbreeding results in increased changes of the emergence of recessive traits. These can be what is called deleterious traits that do not result in a more robust species.
What did Gregor Mendel study?
He studied dominant and recessive genes. He studied pea plants and the traits that they obtained from previous generations.
What did gregor Mendel propose?
Gregor Mendel proposed the idea of separately inherited factors. His work showed that traits remained distinct in the offspring and could sometimes skip generations.
