Why are dominant genetic diseases more rare than recessive diseases?
Imagine you have a bunch of cats, the cats can be green, purple, or any other color. Green and purple cats can be easily eaten by predators but other colored cats are not seen. Purple is a recessive trait which means the cat needs 2 purple genes to be easy prey but green is a dominate trait which…
The Short Answer
Imagine you have a bunch of cats, the cats can be green, purple, or any other color. Green and purple cats can be easily eaten by predators but other colored cats are not seen. Purple is a recessive trait which means the cat needs 2 purple genes to be easy prey but green is a dominate trait which means the cat needs just 1 green gene to be easy prey. Green and purple cats are much less likely to reproduce because they get eaten so often, but since it is necessary to have 2 purple genes often cats who have just one purple gene will live to reproduce and pass that gene along meaning that it is possible for the entire cat population to have 1 purple gene. But if a cat has 1 green gene he turns green no matter what which makes it less likely that he will live to pass along his dominant gene removing that gene from the population. Human genetic diseases follow that same general idea.
