what are some easily observed (or semi-easily observed) dominant and recessive traits? INTERESTING ones?

Question

I have all of the normal dominant and recessive things that are fairly interesting...PTC tasting, tongue rolling, 1st or second toe longer, hitchhikers thumb, hand crossing. i know there's like, widows peak and stuff but those are boring. what are some easily observed (or semi-easily observed) dominant and recessive traits

Answer 1

eye color, hair color, shape and size of ear lobe...

Answer 2

Most of the others mentioned, but some good fun ones are:

hair on the second joint of the fingers

big toes smaller than the next toe on the foot

index finger and ring finger the same length

many visible hairs on back, shoulders and the extension of hairs on the nether regions

these are all considered recessive genes

Answer 3

"pepered moths" there replaced into no mutations there. there replaced into already 2%. "ten Italian wall lizards" The gene replaced into already there for the cecal valves. It purely were given activated. Thats all. Its like the gene that makes the teeth in hen being activated. there isn't any evolution purely reactivation. "The cane toad in Australia....were got here upon to be higher, hardier, had longer legs making an allowance for more effective velocity" Yeah and individuals were getting higher and North Koreans were getting smaller. Its using food. No mutations in contact. " the finches of the Galapagos ..... Daphne island were got here upon to have advanced smaller beaks extra proper for the smaller nuts" this can okay be using sexual decision. you are able to replace the features of a breed by sexual decision. no one claims that mutations take position. "The Blue Moon Butterfly....this situation shows how a mutation giving an earnings can right now spread for the era of a inhabitants." BS no mutation replaced into reported. this can be defined by many aspects. to illustrate the butterfly ought to have discovered to hid the egg more effective. "drug resistant" doesn't educate something. it truly is been common for thousands perhaps 1000's of years that we can boost immunity. that's an version of the immune gadget. It has no longer something to do with evolution. "e coli" different micro organism have the flexibility to digest citrate. E. coli actually have those genes they're only no longer many times activated.

Answer 4

blue eyes and i recently learned in Chem that only some people could smell ammonia. We made some and only half the class could actually smell it. That's neat i think, similar to the PTC tasting

Answer 5

eye color and hair color
