In what stage of meiosis would chiasma most likely be observed?

Ans.

Chaisma is defined as a contact point or physical link between two the two non-sister chromatids that belong to homologous chromosomes.  It is responsible for the exchange between genetic material, which is known as crossing over and is important for genetic variations.

Crossing over and chaisma formation occurs in meiosis cell division generally as it is responsible for chromosomal segregation in gametes. Formation of chaisma takes place during prophase I diplotene stage.

Thus, the correct answer is 'diplotene stage.'

Prophase I

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.

genetic variation will increase because of a new habitat and food source.
