Question

Nearly all life cycles have both haploid and diploid phases. Usually, the transition from haploid to diploid takes place __________.

a) During fertilization
b) During meiosis
c) During mitosis
d) During cell division

Answer 1

The transition from haploid to diploid in life cycles takes place during fertilization.

Step-by-step explanation:

The transition from haploid to diploid takes place during fertilization. Fertilization is the process in which the haploid gametes, one from each parent, fuse together to form a diploid zygote. This zygote then undergoes mitosis and cell division to develop into a multicellular diploid organism.
