Why is having six fingers dominant shouldnt it be recessive since no one has it?

Question

i need to kind a reason why a lot of people don't have six fingers. What happen? did all people with six fingers die?

Answer 1

polydactyly (having extra digits) is a dominant trait. However, dominance does not mean it will be prevelant in a population; most everyone just happens to be recessive.

Answer 2

Six Fingers Dominant Trait

Answer 3

6 Fingers Dominant Trait

Answer 4

You're very observant and have learned a lesson here. Just because a trait is dominant doesn't automatically make it more abundant. This phenomenon can be explained by the Hardy-Weinberg Equilibrium. It's a mathematical explanation that
shows why frequencies of a gene in a population tends to remain the same. In other words, if only .1% of a population has a certain trait, like an extra finger, this percent will remain the same (even if it's dominant) for many generations.
This mathematical concept is also used by biologists to explain how evolution occurs.

Answer 6

Well with a dominant trait, you have to subtract and omit all poloydactyly's which emulate sufficient data onward a past substance. 6 toes + 6 fingers = 12 poly. forumlae 12 / 6 = 2 + 2 = 4 x 2 = 8 formulae The extra digits produced also contain enough to amount to a substantial amount of representation. 14.677% is the final solution.
