The allele at locus B is likely to be lethal when combined with the allele for barred eyes.
a. true
b. false
Ans: b. false
(We know that the Bar eye allele sits very closely to locust B, which mean after cross-over, the Bar allele and locus B are likely still together (combined) and we know that offspring are produced with Bar eyes- so it is not lethal or there would be no offspring to observe the bar-shaped eyes.
