Question

Many plants produce male and female sex cells in the same flower. They can produce seeds by self -pollination or cross – pollination. a) Describe the difference between these two processes. b) Explain why cross pollination is better.

Answer 1

Answer:

. attractive hypothesis to ). DAPI staining demonstrated that explain the phenotypic differences between the four pollen grains from both rop2-m1 and wild-type homozy- alleles with insertions in the first intron is that a large gotes were trinucleate (Figure 8, C and D). Moreover, MuDR-related element (rop2-m2, -m5) exerts a much in vitro germination assays have thus far failed to reveal stronger deleterious effect on splicing than a smaller altered pollen tube morphology or reduced germina- element does (e.g., Mu1 and Mu8, in rop2-m3 and -m4, tion frequency in mutant as compared to wild-type pol- respectively).
