Q. Show the Embryological Evidence?
Embryology is the study of the successive stages of sporogencsis , gametogenesis and the growth and development of the embryo. The number of nuclei in the pollen grains at the time of pollen dispersal is either two or three. Double fertilisation is an example of embryological unity throughout the angiosperms. Based on the number of cotyledons, monocotyledons are separated from dicotyledons. The binucleate pollen is derived. Embryology has had systematic significance in the grass family, where with several other characters it has been used to revise the family's classification. In animals the embryological evidence is of great significance, e.g. the Anopheles maculipennis complex is broken into a number of sibling species on the basis of their egg structure. In Dacus oleae and ceratitis capitata.(fruit flies) the whole eggs are separated on the basis of the character of anterior pole and the whole classification of white flies is primarily based on the structure of their pupae.
