In nitrovian flyti, with biological systems identical to those of earth fruit flies, there is a phenotype, tofutti, in which the flyti are strictly vegetarian. if a true-breeding female (non-vegetarian) is mated with a vegetarian male, they produce 1000 f1 offspring in the following counts: 523 non-vegetarian female flyti; 477 non-vegetarian male flyti. in a reciprocal cross, the numbers of f1 offspring produced are: 502 non-vegetarian female flyti; 498 vegetarian male flyti. the most likely explanation for these results is:
a. the gene coding for tofutti is x-linked dominant.
b. the gene coding for tofutti is autosomal dominant and homozygous lethal.
c. the gene coding for tofutti is x-linked recessive.
d. there is insufficient information to answer this question.
e. the gene coding for tofutti is autosomal recessive and homozygous lethal.
