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.
The other members o the groups help them to survive by taking care of the pups.If it want for them maybe they would die.So the social or connection they have with them will help them to connect with them when they grow
