what is the inheritance of a dominant trait?

b. the trait will be observed in every generation because only one dominant trait will show and whether they have one dominant or two dominant alleles, that trait will show in every generation.

> a. every affected person must have two affected parents> This somewhat seems right to me, but i am still not sure what the choice is explaining. If there was no (e) option. I would have choosen this.

b. the trait is observed in every generation
> No, its not until the parents are atleast heterozygously dominant.

c. an affected heterozygote will transmit the allele to all of his or her offspring
> No, it won't, one of the allele transmitted will be dominant, but the other allele will be recessive.

d. all of the above
> So, this one goes wrong.

d. none of the above (Seems liable to me)
