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.
