Scientists are attempting to make a chicken look like a dinosaur ("dino-chicken")by using drugs or proteins to turn on certain homeotic genes during the development of a chicken embryo. If the scientists are successful in creating both male and female "dino-chickens," and then the "dino-chickens" mate together, what type of offspring would the two "dino-chickens" have?
A)a male or female "dino-chicken"
B)a male or female normal chicken
C)You can't know for sure because of random fertilization.
D)You can't know for sure because it depends on whether the modified homeotic genes are dominant or recessive.

The offspring would be normal chickens because the genetic modifications made to the "dino-chickens" are not heritable; they do not alter the DNA in the germ cells (sperm or eggs).
