Answer:
The correct answer is - homologous chromosome exchange genetic information during prophase I.
Explanation:
Genetic variation or diversity in the offspring of an organism comes from the process of crossing over which takes place in gametes formation during meiosis.
In prophase I of meiosis I, the recombination or crossing over takes place in which the homologous chromosomes pair joins with a structure called synapsis, and segments or the arms of the non-sister chromatids are exchanged during the production of the gamets.
Incorrect they are usually single-celled organisms.

Answer:
1/4
Explanation:
Given the genotype of parent plants: Ggpp and ggPp. The parent plant with Ggpp genotype will form two types of gametes in 1:1 ratio= Gp and gp.
The parent plant with genotype ggPp would form two types of gametes in 1:1 ratio= gP and gp. The random fusion of these gametes from two parents would obtain progeny in the following phenotype ratio=
1/4 yellow purple: 1/4 yellow white: 1/4 green purple: 1/4 green white
Therefore, 1/4 of the total progeny would be "yellow and white".
