Adominant allele h reduces the number of body bristles in fruit flies, giving rise to e "hairless" phenotype. in the homozygous condition, his lethal. a dominant allele s has no effect on bristle number except in the presence of h, in which case e single s allele suppresses the hairless phenotype, thus restoring the bristles however, 5 is also lethal in homozygote. a. whet ratio of flies with normal bristles to heirless individuals would we find in the live progeny of e cross between two normal flies both carrying the h ellele in the suppressed condition? b. when the hairless progeny of the previous cross ere crossed with one of the parental normal flies from (a) (meaning a fly that carries h in the suppressed condition), what phenotypic ratio would you expect to find among their live progeny?
