A cave explorer found a bunch of Megalodon sharks teeth in a cave in the middle of the Arizona Desert. What best explains why he would discover shark fossils here?
Megalodons would hunt their prey on the surface as well the ocean

Gary Goldfish is heterozygous for dark orange color. Ginny Goldfish is homozygous dominant. Their baby has light orange color. Is Gary the father?
Yes, because the light orange color is dominant
No, because there is no way they could produce a homozygous recessive baby
Yes, because Ginny has two alleles for light orange color, so their baby could be light orange
No, because Gary does not have the allele for light color.
