Vith three COlors: Red, Yellow, and Green. You cross a true-breeding Red line and a true- breeding Yellow line. The F, progeny are all Red, with no traces of Yellow or Green pigment present. Then, you take the F, progeny and cross them to each other. In the F2 generation you see a 3:1 phenotype ratio of Red : Yellow progeny. What is the most likely conclusion you can draw from these results?

Question
Can you please find the best conclusion answer for this problem?
Suppose you have a species of butterflies with three different colors:
Red, Yellow, and Green. You cross a true-breeding Red line and a true-
breeding Yellow line. The F, progeny are all Red, with no traces of
Yellow or Green pigment present. Then, you take the F, progeny and
cross them to each other. In the F2 generation you see a 3:1
phenotype ratio of Red : Yellow progeny. What is the most likely
conclusion you can draw from these results?
Red and Yellow are two alleles at the same locus, where Yellow
is dominant and Red is recessive.
O Red, Yellow, and Green pigments are determined by co-dominant
alleles at the same locus.
O Red and Yellow are two alleles at the same locus, where Red is
dominant and Yellow is recessive.
O Red and Yellow are encoded by two alleles at the same locus,
which show incomplete dominance.
O Red, Yellow, and Green pigments are sex-linked alleles, so
Green only shows up in certain crosses.
