the answer is D because dominant genes will show over recessive genes. if it’s a dominant and a recessive pair then the dominant phenotype will show. if it’s both recessive then the recessive type will show. recessive only shows if they’re both recessive. so when you look at the dna you see if they’re both recessive, or if there’s a dominant phenotype and then you look at the key. Not sure if i explained that very well but i hope this helps!!
