Detailed explanation-1: -Onions can reproduce from bulbs. One parent bulb generates daughter bulbs with duplicate genetic information. Which is the most likely advantage of this kind of reproduction? Large quantities of individuals can be produced rapidly.
Detailed explanation-2: -Asexual reproduction produces plants that are genetically identical to the parent plant because no mixing of male and female gametes takes place.
Detailed explanation-3: -The advantages of asexual reproduction include: the population can increase rapidly when the conditions are favourable. only one parent is needed. it is more time and energy efficient as you don’t need a mate.
Detailed explanation-4: -Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote.
Detailed explanation-5: -Sexual reproduction has the potential to produce tremendous genetic variation in offspring. This variation is due to independent assortment and crossing-over during meiosis, and random union of gametes during fertilization.
