The term ‘Crossing over’ was used by Morgan and Cattell. It is a process in which there is exchange of chromosome segments between non-sister chromatids of a homologous chromosomes. It occurs during pachytene stage of prophase I of meiosis cell division.
Significance of crossing over:
- Crossing over provides genetic variation in all sexually reproducing organisms.
- It creates new combination of genes or genetic recombination and produces hybrids.
The answer is false If it was true it would say, Prokayotes are is smaller than a eukaryotes.
Bees go out of the hive in search of flowers with nectar by sensing static electric zaps with there small hairs. When they do find a flower they land and start sucking up the nectar in the process pollen falls on their coat and they carry it to the next flower to suck nectar from. the nectar is brought back to the hive inside the bees and is thrown up as honey wich the lave eat and if a lave is to become a queen they are fed royal jelly. <span>Royal jelly is a white secretion produced by young female worker </span>bees<span>.
