Answer;

  • radiometric dating of rocks
  • fossil evidence
  • gradual processes of rock

Radiometric dating confirms that Earth is ancient and explains how extremely slow processes can result in major changes to Earth’s surface.

2. A heterozygous trait is one that has both allele forms (in this case, d and D. If both of the parents are Dd, the offspring will also be Dd, and therefore, he has 1/2 chance of being born deaf.

3. Both you and your spouse will be heterozygous (Ee), therefore, since unattached earlobes are dominant

3.1 When two heterozygous traits are bred, you will get the following combinations: yy, Yy, Yy and YY. Which means that your offspring had a 1/4 chance of having attached earlobes, and that is what happened.

3.2 The third option is incorrect, because when you breed 2 homozygous recessive (ee) traits, all of your offspring will be homozygous recessive (ee), which means that the parents would have to be homozygous recessive, but, they cannot since the dominant trait has applied to them.
