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.

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.


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.

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.


How do traits appear in the next generation?

Phenotypic traits are how certain, inherited genes are expressed.During reproduction, both the mother and father gives their child a chromosome, which often results in the child displaying traits similar to his/her parents'.
