What type of of scientific statement is defined as a hypothesis or group of hypothesis that can be accepted as true based on repeated experimentation with similar results?

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
