Transcribed Image Text:Bar eye in Drosophila is X-linked and exhibits incomplete dominance. Wild-type females
have an average of 810 facets in the eye, while homozygous Bar females have an average
of 59 facets. Heterozygous females have a kidney-shaped eye with an average of 447
facets. Males have either wild-type-shaped eyes with about 810 facets or Bar eyes with
about 60 facets.
