Answer:
C
Explanation:
Because the newts with this mutation have faster reflexes, they are able to evade predators much better than the normal newts. This increases their chances of survival hence are more likely to reach reproductive age than the normal newts. Therefore they have a higher probability of passing their genes to the next generations. With each generation, newts with the mutated gene will increase.
Since the male and the female have recessive alleles of this gene, all of their offspring will be like that too.
rr x rr cross will result in 100% of the offspring with the genotype: rr
R- dominant (but none of the parents has this allele)
r- recessive
