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.
What else can I help you with?
Do recessive traits have the potential to skip generations?
Yes, recessive traits can skip generations because they can be carried in the genes of individuals without being expressed in their physical characteristics.
When studying a pedigree how do scientists determine if a trait is dominate or recessive?
dominant only appears in the F1 generation as 4 recessive stays hidden or masked in the F1 generation
How do you know from a pedigree diagram if a trait is dominant or resessive?
If a trait is dominant, it will appear in every generation where at least one parent has the trait. If a trait is recessive, it can skip generations and may appear in offspring of parents without the trait. Dominant traits are usually expressed in every generation, while recessive traits can "hide" and reappear later.
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.
What term describes inherited traits that are invisible?
Recessive traits are inherited traits that are masked or not expressed when an individual possesses a dominant allele for the same characteristic. These traits can remain hidden through generations and only manifest when the individual inherits two recessive alleles.
Do recessive traits have the potential to skip generations?
Yes, recessive traits can skip generations because they can be carried in the genes of individuals without being expressed in their physical characteristics.
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
When studying a pedigree how do scientists determine if a trait is dominate or recessive?
dominant only appears in the F1 generation as 4 recessive stays hidden or masked in the F1 generation
When using a pedigree chart you can distinguish between recessive and dominant traits because?
The two most straight forward ways are: - If both parents have the trait, and one of their children does not, it must be recessive. - If neither parent has the trait, and one of their children does, it must be dominant.
How do you know from a pedigree diagram if a trait is dominant or resessive?
If a trait is dominant, it will appear in every generation where at least one parent has the trait. If a trait is recessive, it can skip generations and may appear in offspring of parents without the trait.

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!
Is the trait being studied in the pedigree recessive or dominant?
This cannot be determined solely from a pedigree without additional information. The inheritance pattern of a trait can be deduced from the way it is passed down within a family and how it appears in the pedigree. Dominant traits will typically appear in every generation, while recessive traits may skip generations.
Why is ginger the only hair colour to skip generations?
Becasue red hair is caused by a recessive relatively rare gene.
Do autosomal dominants skip generations?
Autosomal dominant traits typically do not skip generations because affected individuals usually have a 50% chance of passing the trait on to their offspring. However, the trait may appear to skip generations if carriers of the trait do not show symptoms or if there is a lack of complete penetrance.
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!
