Question

What is true about dominant traits?

A.Dominant traits are unable to be passed on to offspring

B.Dominant traits take longer to be expressed than recessive traits.


C. Dominant traits will replace recessive traits in an organism over time

D .Dominant traits will be expressed if one dominant allele is present.

Answer 1

D. Dominant traits will be expressed if one dominant allelle is present.

Explanation: Lets say T (tall) was dominant over t (short) If the phenotypes are Tt or TT (where a dominant allelle is present in both) the dominant trait of tallness is expressed. However if there is no dominant allele and the phenotype was tt, the offspring would be short and so the dominant trait wouldn't be expressed.
