Final answer:
The gamete C could not result from the given parent cell. The phenotype of the fly that grows from the fertilized cell will be normal wings, brown body, legs on head, and red eyes. Offspring B could not arise from the given parent cells with the shown chromosomes.
Step-by-step explanation:
When considering the traits of body color and eye color in fruit flies (Drosophila melanogaster), we can determine the possible gametes and phenotypes based on the information provided. The given parent cell has a wild-type phenotype, which means the male fly has a gray body and red eyes, while the female fly has a black body and cinnabar eyes. In the F1 progeny, all flies displayed a wild-type phenotype, indicating that the alleles for black body and cinnabar eyes are recessive. Thus, the gamete C could not result from the parent cell.
Regarding the phenotype of the fertilized cell, the traits observed include normal wings, a brown body, legs on the head, and red eyes. These traits are based on the wild-type phenotype, as mentioned earlier. Therefore, the phenotype of the fly that grows from the fertilized cell would be normal wings, brown body, legs on head, and red eyes.
For the third question, if we assume crossovers can occur between chromosome pairs in the parent cells, the offspring that could not arise from the given parent cells with the shown chromosomes is Offspring B. This conclusion can be drawn by analyzing the possible combinations of chromosomes resulting from crossover events between the homologous pairs.
