Answer:
Singed bristles/vestigial wings and normal bristles/normal wings
Explanation:
The recombinant progeny might occur due to the crossing over of the homologous chromosomes in case of the linked genes. This progeny are different from their parent progeny.
The F1 offspring obtained from the given cross in the question results in the normal wings and normal bristles ( SsLl). This progeny was crossed with singed bristles and vestigial wings (ssll). The progeny obtained from their cross are 'Sl' and 'sL' ( parental type ) and SL' or 'sl' ( recombinant).
Thus, the correct answer is option (D).
Answer:
Low cost has low quality whereas high cost has high quality.
Explanation:
If the main criterion was keeping the cost of materials as low as possible so he must used the materials of low quality for their work because the low quality materials are made of cheap material while on the other hand, if the main criterion was getting the best performance from the material so he has to used the materials of high quality. The high quality materials are very expensive but its performance is excellent as compared to cheap materials.
