At fertilization, the union of the sperm cell and the egg cell results in a (zygote/gamete) that contains “unit factors”. These unit factors are later referred to as (DNAs/genes). A variant of a gene controlling the same trait is called (a chromosome/an allele). The variants of a gene for a trait may exist in pairs. By the time that the offspring is capable of producing its own sex cells or gametes, the members of these paired unit factors will (segregate, join). Then, they assort (independently/dependently) into the newly formed gametes. These events occurs during (mitosis/meiosis). Each gamete will contain only one member of every paired unit factors.
