Yes. Air can be separated through fractional distillation. The air must be cooled to a liquid first. Considering nitrogen oxygen and argon all have different boiling points, the liquid air mixture can be heated very gently and carefully in a fractionating column. Each element will eventually vaporise and they can be condensed and collected at different points up the fractionating column because they each have different boiling points.
Answer:
12
Explanation:
Parent 1 : normal petal, long stamen
Parent 2 : short petal, normal stamen
F1 generation has all short petal and normal stamen plants so these two are the dominant traits.
F2 generation will have a mixed progeny. Out of them normal petal, long stamen and short petal, normal stamen will be parental combinations since they were the phenotype of the original parents.
Distance between the two genes is 24 cM and distance between genes = recombination frequency. Hence, recombination frequency here is 0.24.
Out of 100 total plants in F2, 100*0.24 = 24 will be recombinants. Out of 24, 12 will be short petal, long stamen recombinants and other 12 will be normal petal, normal stamen recombinants.
Hence, out of 100 plants 12 are expected to have short petals and long stamens.
