To solve the question, we need to understand the genetic traits involved. In this case, it seems that “E” represents the allele for the three-eyed trait (dominant), while “e” represents the allele for the two-eyed trait (recessive).
Given that “E” is dominant over “e,” we can analyze the potential genotypes of the offspring:
1. If we assume a cross of heterozygous parents (Ee x Ee):
– The possible offspring combinations would be:
– EE (3-eyed): 25%
– Ee (3-eyed): 50%
– ee (2-eyed): 25%
However, if you are given data to consider that the outcome is particularly set to 0:4 (implying no EE or Ee offspring), you might assume conditions that would yield:
– 0% of 3-eyed offspring
– 100% of 2-eyed offspring (if both parents are homozygous recessive, ee x ee).
### Answers:
– What percentage of offspring would have 3 eyes? 0%
– What percentage of offspring would have 2 eyes? 100%
– The ratio for offspring with three eyes is 0:4.
– The ratio for offspring with two eyes is 4:0.
– Three eyes is the dominant trait.
– Two eyes is the recessive trait.
