In fruit flies, the dominant H allele gives rise to a hairless phenotype, hh gives rise to normal body bristles, and the HH homozygote condition is lethal during an embryonic stage. The presence of a dominant S allele suppresses the effect of the dominat H allele with respect to the body bristles phenotype such that normal body bristle phenotype is restored when only one dominant H allele is present (HH is lethal irrespective of the S or s alleles). The ss genotype has no effect over the H allele and the SS homozygote condition is also lethal during an embryonic stage. What would be the expected phenotypic outcomes among the surviving offspring from the following cross: HhSs X hhSs 2 normal body bristles: 1 hairless 7 normal body bristles: 2 hairless 1 normal body bristles: 1 hairless 3 normal body bristles: 1 hairless 5 normal body bristles: 1 hairless
In fruit flies, the dominant H allele gives rise to a hairless
HhSs X hhSs
2 normal body bristles: 1 hairless |
7 normal body bristles: 2 hairless |
1 normal body bristles: 1 hairless |
3 normal body bristles: 1 hairless |
5 normal body bristles: 1 hairless |
