Question
In Drosophilia, S = normal, s = sable body: W = normal, w = miniature wing. In a cross between a heterozygous normal fly (heterozygous for both traits) and a sable-bodied, miniature-winged fly, the results were 90 normal flies, 90 with a sable body and miniature wings. 11 with a normal body and miniature wings, and 11 with a sable body and normal wings. Show your work What inheritance pattern explains these results? Why is the explanation for the small number of 11 insects with normal body and miniature wings, and a sable body with normal wings?Explanation / Answer
This is a case of sex linked inheritance.11small numbers are of those females which are having both alleles for the concerned character ie for miniature wings and sebal body.carriers as well as males will not show these features as these are recessive and linked to x chromosomes
