A new human species was found on a distant planet, whose genetic inheritance and process of reproduction is identical to that of humans on earth, however, their phenotypes are much different. You are tracking two phenotypes in this new species: eye shape and tail size. The single gene that controls eye shape (gene E) is unlinked from the single gene that controls tail size (gene T). Square eyes is the dominant eye shape and round eyes is the recessive eye shape. Long tail is the dominant tail size and short tail is the recessive tail size.

1. An individual of this new species is heterozygous for gene E and heterozygous for gene T. What is their genotype and phenotype? (note: upper-case letters indicate dominant alleles and lower-case letters indicate recessive alleles)

2. Two individuals, who are both heterozygous for eye shape and tail size, mate. Which of the following is a correct statement about the phenotype ratios expected for their offspring?

3. From the mating described above, what proportion of ALL of the offspring in will be heterozygous for both traits?
