- Q4Which of the following is one gene that the offspring gets from each parent?chromosomerecessive traitdominant traitallele30s
- Q5Which best explains why you can look like either of your parents of a combination of both of them?Only one parent contributes the genetic material needed and it is always the dominant genes.Each parent contributes one-half of the genetic material needed and some genes are dominant and expressed.Each parent contributes one-half the genetic material needed and only the dominant genes are passed on.Each parent contributes one-half of the genetic material needed but and only recessive genes are expressed.30s
