Answer: Well, lets think about it they both have common ancestry . Two common things you can take is you can ask yourself what different parts one has and what one does not have to find the answer. for any more help let me know!
Explanation: Have a great day :)
Because the three-horned alien is heterozygous, we know that three must be dominant to four, because the gene for the three horns is "hiding" the gene for four horns. Therefore, the three-horned alien has the genotype Tt (T for three horns, and t for four horns). The four horned alien must be tt, because that is the only way that a recessive trait may be seen. If you solve the punnet square on a cross between Tt and tt, you end up with half three (heterozygous) and half four (homozygous recessive) it is a bit easier to explain with something a little "closer to home" if you want me to explain it again, just say so, I don't mind!
1. allele
2. recessive
3. gene
4. genotype
5. phenotype?
6. dominant
