yes it can skip a generation, since it is a Mendel inheritance. and it is a reccesive trait. therefore offspring's can have two unaffected parents but chances are both parents might be carriers

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


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.


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.


How can recessive traits skip generations?

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.


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

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.


Do heart attacks skip a generation?

While gallbladder disease may have genetic components, it does not keep track of the last generation affected. It can "skip" a generation or affect the children of affected patients.

Why is sickle cell anemia most common in black individuals?

Sickle-cell anemia is caused by a defective gene that produces an abnormal form of hemoglobin which is called hemoglobin S. And this gene is particularly common in Western Africa and people of Western African Ancestry. An estimated 8 to 12 percent of all African Americans carry the sickle-cell gene.
