Consider this hypothetical example. Bluegills can either have green eyes or brown eyes. The trait is controlled by a single gene. Bluegills can either have long or short fins. This trait is controlled by a single gene that is on a different chromosome from the eye color gene. Having green eyes is dominant (G), while having brown eyes is recessive (g). Having long fins is dominant (L), while having short fins is recessive (1). Your not-so-famous instructor will mate a male and female that both are heterozygous for eye.color and heterozygous for fin length. What phenotypic ratio is expected from this mating? O 1:1:1:1 O 1:2:1:2:4:2:1:2:1 O 3:1 O 9:3:3:1

Question
Consider this hypothetical example. Bluegills can either have green eyes or brown eyes. The trait
is controlled by a single gene. Bluegills can either have long or short fins. This trait is controlled by
a single gene that is on a different chromosome from the eye color gene. Having green eyes is
dominant (G), while having brown eyes is recessive (g). Having long fins is dominant (L), while
having short fins is recessive (I). Your not-so-famous instructor will mate a male and female that
both are heterozygous for eye color and heterozygous for fin length. What phenotypic ratio is
expected from this mating?
O 1:1:1:1
O 1:2:1:2:4:2:1:2:1
O 3:1
O 9:3:3:1
