Recessive traits like red hair can skip generations because they can hide out in a carrier behind a dominant trait. The recessive trait needs another carrier and a bit of luck to be seen. This means that it can sometimes take a few generations to finally make its presence known.

Can blue eyes skip a generation?
This is because you each only have blue versions to pass on to your children. That means that your kids will most likely all have blue eyes. So once dominant traits like dark eyes aren’t passed on to the next generation, they can be “lost.” Genes can be passed on from generation to generation.
Why do some conditions skip a generation?
Autosomal recessive These are the conditions that aren’t seen in every generation. That is because when both parents are carriers of mutations in the same gene, they have a 25% chance with each pregnancy to have a child with the disorder. Carriers of autosomal recessive conditions usually do not have symptoms.
Is lip size genetic?
They are an extinct group of ancient humans, who lived tens of thousands of years ago. The team found that the gene, TBX15, which contributes to lip shape, was linked with genetic data found in the Denisovan people, providing a clue to the gene’s origin.

How genetic is height?
Scientists estimate that about 80 percent of an individual’s height is determined by the DNA sequence variants they have inherited, but which genes these variants are in and what they do to affect height are only partially understood.
Are sons taller than their mothers?
If a mother and father are the same height, their daughters will be roughly the same height, but their sons will be taller. This is because in order for the mother to be the same height as her husband, she must have more of the other ‘tall genes’ than him, and these get passed onto her sons.
