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.
Some traits may skip a generation due to the way they are inherited. This can occur if the trait is recessive and carried by a parent who does not show the trait themselves. In the next generation, when both parents pass on the recessive trait, it can manifest in the offspring.
Yes, a trait can skip a generation. It happens with the "Recessive" genes. If you look into the middle-east, you can see that there are more diseases in the families because over there, people marry their cousins and so on. Since that occurs, the genes are similar and both have the disease making it a dominant trait for the offspring.
because it just does. haha jkjk. the real answer is that since the tall plants are dominant, then the recessive plants( shot plants) will be overcome. However, they do still stay there so when they.....interbreed.....then the short plant comes bak
A physical trait can "skip" a generation because traits carried and expressed in an organism by genes can be transmitted but not be observed. This recessive gene carries the information for the trait but is not expressed, therefore it is there but not seen. Recessive genes can recombine to form dominant genes in later generations, which once again give rise to the previously "skipped" trait.
AA X AA
= all Aa
Aa X Aa
= 2 Aa, 1 AA and the expression of the homozygous recessive; AA
As you see, simply put, some traits are masked by dominant traits in one generation but can be brought to expressivity in the next generation.
Recessive traits skip generations because the recessive allele is masked in the heterozygous state in one generation and is expressed in the homozygous state
in the next generation. In small populations with a low frequency of recessive alleles a recessive trait can go several generations before it is expressed.
They can, if the traits are recessive. You would need two copies of the traits for them to be expressed. If you had one dominate trait and one recessive, only the dominate would be expressed. Experiments were done with sweet peas and tall peas are dominate but short ones are recessive. If you cross the two, only the tall genes are expressed. You would "see" only tall pea plants. It would seem that the traits had skipped the generation but they are just recessive. If two plants are crossed that carried both traits, some of the plants will be short (1/4).

Your parents are dark complected but you have blonde hair and green eyes Why?
Having blonde hair and green eyes is often a result of genetic variation. Traits like hair and eye color are controlled by multiple genes, and it's possible to inherit different combinations from your parents that result in a unique appearance. This variety is what contributes to the diversity in human populations.
How do traits appear in the next generation?
Traits appear in the next generation through the inheritance of genes from parents. Offspring receive a combination of genes from both parents, which determine the physical and behavioral characteristics they will exhibit. This genetic information is passed down through generations, leading to the expression of traits in descendants.
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.
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
Mendel accounted for the observation that traits which had disappeared in the F1 generation reappeared in the F2 generation by proposing that?
Mendel proposed the concept of dominant and recessive traits, where recessive traits are masked in the F1 generation but can reappear in the F2 generation when two carriers of the recessive trait combine and show the trait. This is known as the Law of Segregation, where pairs of alleles separate during gamete formation, leading to the reemergence of hidden traits.
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
If father and mother have brown eyes and brown hair can baby have blonde hair and blue eyes?
If it runs in the family, yes. Some traits skip a generation.

Can hole in the heart skip a generation and be the cause of down syndrome in a grandchild?
can not be passed from generation to generation
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.
In which generation were recessive traits visible Mendel's experiments?
Recessive traits were visible in the F2 generation of Mendel's experiments, where the offspring of the F1 generation showed a 3:1 ratio of dominant to recessive traits.
Can height skip a generation?

What is the name of the study of heredity traits of an organism?
Genetics Genes are the DNA that pass our hereditary traits from generation to generation
