The dna of the young dragons was analyzed. all offspring were homozygous at all loci. they were not identical clones of their mother: their genetic makeup was different from mum. the offspring were not genetically identical to one other. 13. how were the offspring produced?

As offspring are considered to be progeny or brood they not totally affected by mentioned factor but it's behavior they are produced by mating only

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
