Question

Traits that typically will be expressed in offspring only if they inherit two copies of the genes for the trait are called _____ traits. A. recessive B. dominant C. expressive D. developmental i think it is B

Answer 1

The dominant traits are expressed if only one copy of the allele is present. That is to say, it's dominant over the other, unexpressed allele. So I think the traits which are only expressed if two copies are present are called recessive.

Clear?

Answer 2

no

Answer 3

OK. One gene with two different alleles. Alleles are "copies" or "versions" of each gene. Alleles can be dominant or recessive. If only one version is strong enough to be expressed regardless of what the other allele is, it's called a "dominant" allele. If the trait is expressed only when the same two alleles are there (i.e., when the alleles are not dominant) it's called recessive.

So I think the answer is A, recessive.
