Answer:
Combined parenting leads to faster reproduction
Explanation:
Genetic diversity or variations in the physical appearance of organisms is caused by genetic or environmental factors. Reproduction brings about variation through gamete formation, fertilization and mutations.
During prophase 1 of meiosis, homologous chromosomes pair to form bivalents. The crossing over at the chiasmata results in new gene combination and variations.
Fertilization permits parental genes to be brought together. This causes variations in members of the same family.
Mutation is the spontaneous change in genetic make-up. These changes may be inherited by offspring bringing variations. However, combining parenting does not increase genetic diversity.
Counter current involves blood in the capillaries flowing in the opposite direction to the flow of water flowing over them. Gases diffuse faster from one area to another when the concentration difference between the two areas is at its greatest, as compared to when the concentration difference is low.
