In fruit flies white eyes are dominant and red eyes are recessive what is the genotype for a purebred fly with white eyes EE Ee eE ee

According to the information in the question, the correct genotype for a pure breed fly with white eyes is EE.

Explanation:

Genotype for Pure breed organisms are made up of two similar alleles at the loci. That is pure breed genotypes are homozygous chromosome. That means it could be recessive alleles or dominant alleles.

In reference to the question, it can be inferred that white eyes in fruit flies are controlled by dominant alleles, which means that the presence of at least one of this allele will make the offspring to exhibit white eyes, therefore, the genotype for white eyes can be represented as: EE or Ee.

While the red eyes is controlled by recessive allele, therefore this will be represented as ee. The question requested for the genotype of the pure breed white eyes fruit flies, therefore combining the two explanations given above, the correct answer will be EE.
